The latest revision of Intrasis is 6431, published 2022-03-21.
If you already have an installation of Intrasis 3.2 you can patch to a later revision by downloading and installing the Intrasis Patch.
Unzip the downloaded file on your computer and run the setup file for your version of ArcGIS e.g. Intrasis_Patch_188.8.131.5231_[ESRI_10.8].exe or any of the other ESRI versions we support. Make sure to run as administrator. The patch will be installed, and it will only take a few minutes.
If your computer doesn’t have correct versions of e.g. Microsoft Visual C++ 2013 Redistributable, needed by Intrasis, they will also be installed. Some computers might need a restart after installation of external packages.
