in Oasis montaj

I used windows installed apps → uninstalled oasis. Then installed Oasis again (Geosoft 2025.2.1 Setup 53 2026.02.05.exe).

Any python extension doens;t work anymore. Yielding the below error dialog.

Indeed, folder

C:\Program Files\Geosoft\Desktop Applications\python

is completely empty.

I am pretty sure that
packages/python-3.11.9-embed-amd64-om.zip

is supposed to be unpacked during the installation to that python fodler. Is this a bug in the installer?

    Hi @VictorSavenije. You are partially correct. The contents of that zip are unpacked into the python directory, but there are a few extra steps being done. Behind the scenes, there is the following "post install" action the installer runs that sets everything up:

    C:\Program Files\Geosoft\Desktop Applications\bin\geosoft.installer.utility.exe" -install_python -workingdir="C:\Program Files\Geosoft\Desktop Applications\bin" -python_path="C:\Program Files\Geosoft\Desktop Applications\packages" -destination="C:\Program Files\Geosoft\Desktop Applications\python"

    You can run this manually after install and if successful it should resolve your issue.

    I was unable to reproduce this problem when running the installer, but sometimes there are machine-specific issues. You can check for the outcome of the "post-install" utility action by looking at the log file generated during installation. Its at %TEMP%\Geosoft_Desktop_Applications_DATETIME_NUM_GeosoftPackageX64.log

    Thanks for the information. Running geosoft.installer.utility.exe indeed solved it too.

    But I actually I did not tell exactly how I got the issue: I uninstalled, then installed RELEASE_DESKTOP_APPLICATIONS_2025.2.0_42_11_27_2025_setup.exe

    (don't know where our organisation got his from at this moment). That one had the issue. Then I ran Geosoft 2025.2.1 Setup 53 2026.02.05.exe (without first uninstalling).

    Now uninstalled, and ran 2025.2.1 Setup 53 2026.02.05.exe, which installs properly.
