Satellite dishes downloading

This page provides installation files for Manifold SQL for ArcGIS® Pro. You must have an SQL for ArcGIS® Pro serial number to operate installations on this page.

  • Download the installation package you prefer from the options below.
  • Install the package using the installation instructions in the the Install SQL for ArcGIS Pro page.
  • Install SQL for ArcGIS Pro - Illustrated, step by step user manual topic showing download, installation, and activation for both Windows Installer and portable installations.
  • SQL for ArcGIS Pro requires the latest version of ArcGIS® Pro.  Installation packages are automatically updated to track Esri releases of ArcGIS Pro.

Getting Started: Watch videos and read the user manual for a fast start:

Free updates: To update SQL for ArcGIS Pro to the latest release, download and install the latest Edge build or, for Windows Installer users, the latest Base build. Activation status will be preserved.

Cutting Edge or Base ?

SQL for ArcGIS Pro evolves very rapidly. Most people always want the latest version, while others prefer to update less frequently. To meet both needs, Manifold provides both newer (Edge) and older (Base) installations.

Starting at a given Base level, each new Edge build adds more and more capabilities. After two or three months of Edge builds, Manifold updates the current Base build to incorporate new Edge features, and then the cycle starts over with a new series of Edge builds. Each Edge build is a full, standalone build, with no need to install the prior Base build to get the full package with all of the latest features.

  • SQL for ArcGIS Pro Edge - Edge builds provide all new features and bug fixes. Edge builds are issued about every two weeks with an announcement in the user forum. Edge builds are issued as portable installations, making frequent updates easy. Edge builds expire on the third month after they are issued: plenty of time to download the latest Edge build. The User Manual documents Edge builds. Recommended.
  • SQL for ArcGIS Pro Base - Base builds are older versions of Edge builds. They are issued every few months as Windows Installer packages and also as portable installations. Base builds do not time out, and they check for a newer Base build. Base builds do not include the latest features and bug fixes. The latest features discussed in the User Manual will not be in Base builds.

Read the Installations topic for more on SQL for ArcGIS Pro installation packages, including simple instructions for using portable installations.


  • See the Install SQL for ArcGIS Pro User Manual topic for step by step installation and activation instructions with clear illustrations.
  • As of Cutting Edge build 177.2, SQL for ArcGIS Pro no longer includes a 32-bit version. Since ArcGIS Pro is 64-bit and requires 64-bit Windows, this has no downside for SQL for ArcGIS Pro users.
  • Use Cutting Edge build 177.2 for compatibility with ArcGIS 3.0. Base build 177 does not include compatibility with ArcGIS 3.0.
  • Cutting Edge build 177.2 includes only a 64-bit executable. Base build 177 installations include both 64-bit and 32-bit executables.
  • SQL for ArcGIS Pro requires Microsoft .NET and Microsoft Visual C++ Redistributable. If these are not already on your system, see below for links to Microsoft downloads.
  • False alarms from anti-virus programs are common. The SHA checksums published below guarantee safe downloads. See the information below on how to use SHA checksums.
  • Windows Defender may wrongly complain that an installation zipfile contains malware. That is not true and is a false alarm from Defender. Download the file, unzip and run Windows Defender on the resulting files and Defender will report the files are OK.
  • Errors: If there are any errors when unzipping a downloaded file, the file was damaged during download or was not completely downloaded. Try again.

Portable SQL for ArcGIS Pro: Approximately 54 MB. This is the current, Base SQL for ArcGIS Pro build in a portable installation, that includes both 64-bit and 32-bit executables. This installation includes all Manifold features but does not include optional, third-party software to provide IronPython scripting, and to connect to MySQL and PostgreSQL/PostGIS. It does not include the approx 233 MB grids.dat data file containing high-accuracy transformation grids for countries that use grid transformation. The grids.dat data file, database drivers, and IronPython may be downloaded separately for users who desire those.

Important: Running SQL for ArcGIS Pro requires an SQL for ArcGIS Pro serial number. Purchase an SQL for ArcGIS Pro serial number from the Manifold Online Store. Once SQL for ArcGIS Pro is activated on a particular computer all SQL for ArcGIS Pro builds, including Base builds as well as Edge builds, will automatically be activated as well. You can install and uninstall SQL for ArcGIS Pro on the same machine or use multiple different SQL for ArcGIS Pro portable builds without having to re-activate.

Microsoft Visual C++ for Portable Installations

Portable installations of SQL for ArcGIS Pro require installation of Microsoft's Visual C++ Redistributable package. This is not necessary for official SQL for ArcGIS Pro .exe installation packages, which include the C++ Redistributable package and will install if required. Many modern Windows systems will already have this installed. If not yet installed, portable installation users should download Visual C++ 2017 Redistributable installation files from the Microsoft VC Downloads page.

On 64-bit Windows system, install both vc_redist.x64.exe (64-bit) and vc_redist.x86.exe (32-bit). On a 32-bit Windows system, install vc_redist.x86.exe (32-bit).

Important: Use a recent C++ redistributable. Microsoft significantly updated redistributables in November, 2019. Older redistributables will not work.


Visit the SQL for ArcGIS Pro User Manual for detailed information on every aspect of SQL for ArcGIS Pro. Hundreds of examples, including hundreds of lavishly-illustrated, step-by-step examples, show how to use Manifold.

Localization Files - Use Your Language - Click on the link to download a zip file containing user interface localization files for Arabic, Bengali, Chinese (simplified, Mandarin), Dutch, Estonian, Filipino (Tagalog), French, German, Hindi, Japanese, Portuguese, Russian, Spanish, and Turkish languages. See the Localization page for instructions on how to use these files and how to create your own localization file for a new language. 

64-bit Connections to Microsoft Office Formats

By default, SQL for ArcGIS Pro uses Microsoft facilities built into Windows to connect to Office format files such as .db, .html. .mdb, .xls, and .wkx, together with newer Office formats such as .xlsx and .accdb. The same facilities are used to connect to any other use of Access .mdb format, for example, in ESRI's personal geodatabase format using .mdb, or legacy Manifold mfd/mdb format as used in early Manifold releases.

We can connect to Office formats from 64-bit SQL for ArcGIS Pro in 64-bit Windows by installing Microsoft's Access Database Engine 2016 Redistributable package. The 64-bit version of the Access Database Engine provides connectivity to Office formats for 64-bit applications in a 64-bit system. Despite the "Access" name of the package, it supports all Office formats.

Download the 64-bit Access Database Engine from Microsoft's Access Database Engine 2016 Redistributable page. That page provides downloads for X64 (64-bit) and 32-bit versions. Most users will download and install just the X64 version. It is a small download that installs quickly. However, using the 64-bit Microsoft Access Database Engine requires that our Microsoft Office installation is also 64-bit. If we are still running 32-bit Microsoft Office in our 64-bit Windows system, we cannot install the 64-bit Microsoft Access Database Engine.

DLLs for Popular Open Source DBMS Packages

SQL for ArcGIS Pro includes built-in support for GPKG and SQLite using GPKG-style spatial data, RTREE indexes, JSON and GeoPoly. No need to download or install anything extra to read/write GPKG or most SQLite databases.

The SQLite DLL provided is an ESRI package that adds allows connection to Esri mobile geodatabases, which are stored within SpatiaLite files.

The MySQL and PostgreSQL DLLs provided allow connection to MySQL databases and to PostgreSQL/PostGIS databases.

The MySQL and PostgreSQL/PostGIS are third party, open source DBMS packages which require installation of necessary files within the execution PATH of your system. If you are an expert user of MySQL or PostgreSQL/PostGIS you know the drill and have already installed all necessary DLLs. For everyone else, Manifold provides the following sample collections of DLLs for these packages:

The easiest way to install these for use with SQL for ArcGIS Pro is to unzip the within the installation folder for SQL for ArcGIS Pro. That creates an opt subfolder which contains the various DLLs.

The above packages of DLLs are not supported, but they are recommended for use with SQL for ArcGIS Pro.


Of the ten programming languages suppored for programming in SQL for ArcGIS Pro, five languages are built into SQL for ArcGIS Pro and are always available without requiring any additional installation: C#, JScript, JScript.NET, VB.NET, and VBScript. In addition, IronPython and IronRuby are automatically supported by the Command Window when installed. The following zip file provides IronPython for SQL for ArcGIS Pro:

The easiest way to install IronPython for use with SQL for ArcGIS Pro is to unzip within the extras folder of the SQL for ArcGIS Pro installation folder.

IronPython is an open source package that is not supported by tech support, but the above installation is recommended for use with SQL for ArcGIS Pro.

Transformation Grids

When re-projecting a component, SQL for ArcGIS Pro can use high-accuracy conversions that utilize transformation grids for certain regions. Most users will re-project components using default conversions, and thus do not need the grids.dat file. Those users who want to use transformation grids can download and install the grids.dat file, and then the conversion options to use those grids automatically will become available for those coordinate conversions that use them. The grids.dat file is 379 MB and contains in compressed form hundreds of grids enumerated in EPSG, including NADCON5 grids as well as traditional NADCON and HARN NADCON (USA), and NTv2 grids for Australia, Austria, Brazil, Canada, France, Germany, Ireland, Japan, Netherlands, New Zealand, Portugal, Spain, Switzerland, and the UK.

Install the grids.dat file for use with SQL for ArcGIS Pro by placing the file in the extras folder of the SQL for ArcGIS Pro installation folder. The file must be placed in the extras folder itself and not within a subfolder of the extras folder.

SHA Checksums Guarantee Safe Packages

Worried about viruses? Got a false alarm from an anti-virus package? Use SHA checksums to put your mind at ease by confirming you have a safe installation package for SQL for ArcGIS Pro.

SQL for ArcGIS Pro installation packages do NOT contain malware. Use the SHA checksum provided for each download package to confirm your installation package has not been infected and contains no malware. Normally, there is no need to do that unless your anti-virus program reports a problem. Anti-virus programs often report false alarms on perfectly-clean, virus-free files. False alarms are easy to check.

If your anti-virus program reports a problem with an SQL for ArcGIS Pro installation file, you can verify that is a false alarm by using any popular tool (7zip, Microsoft, etc.) to compute the SHA checksum for the installation package you are using. If that SHA checksum matches the SHA checksum published for that package, you know for sure the anti-virus package reported a false alarm.

Windows 10 and other recent Windows editions include the certutil command line utility that will verify the SHA256 checksum for a file. To use certutil open a Command Prompt window and navigate to the folder where the file to be checked is located. Enter the following command line, for example, to check the 32-bit SQL for ArcGIS Pro installation package:

certutil -hashfile manifold-9.0.159.msi SHA256

The utility will provide a computed SHA256 hash code (another name for checksum) for the file:

SHA256 hash of file manifold-9.0.159.msi:
1d 65 79 c2 b7 2f aa 99 7f 40 2c c5 1f 92 80 de 73 0c 4f 4a 4c c5 d2 59 bf 74 7e 79 b8 d4 e0 71
CertUtil: -hashfile command completed successfully.

Compare the SHA256 checksum reported by the certutil utility to the checksum published on this page, ignoring spaces. If they are the same, you know for sure the file you have downloaded is safe.
