Update: .NET 3.5 installation worked out fine via VS 2019 installer, I also added the VS2017 build tools as a precaution since the VM builds take some time. Afterwards build.bat still failed during wix steps, complaining about missing python.exe in PCBuild/win32, not sure if the 32bit interpreter should be fetched/built automagically. Then I tried build.bat -x64, which ran succesfully and provided attached installer. To test it (in administrative shell): 1. git clone https://github.com/bneuburg/python_msi_appendpath 2. cd python_appendpath_installer 3. .\python-3.11.0.7539-amd64.exe /quiet InstallAllUsers=1 AppendPath=1 Include_test=0 Running this in an administrative shell appended InstallDir and Installdir/Scripts to the sytem PATH and created the PATHEXT entries for PY and PYC as well. So far so good! I only noticed the following problem: The first uninstall also succesfully removed all environment variables, however after reinstalling and re-uninstalling, only the PATHEXT were removed, the Python entries in PATH were not removed. This was also independent of the order of software removal (Python Launcher first or second). Thus I had a look at it with orca.exe [1]: 1. Install with appendpath=1 2. Get list of installed msis with: wmic product get /format:csv > software.csv 3. Search for appendpath in software.csv which will return the location of the msi somewhere in c:\windows\installer 4. Right click that file and select 'Edit with Orca' In the environment table it has entries in the following form for a Local Machine install (c.f. for attached screenshot): Environment | Name | Value | Component PATH_LM | =-*PATH | [~]:[InstallDirectory] | AppendPath_LM which according to Microsoft documentation [2] seems to be as intended (add on install, remove on uninstall). But it just doesn't, also see Sascha's comment above. When looking at Orca I also noticed that I forgot to change the position of InstallDirectory in PATH for the CU install from first to last, I updated the PR accordingly. Since you have a Microsoft e-mail address: Any chances you could ask the MSI pros there what is going on? I'll be busy with offline stuff for a few weeks, but if you have any ideas how to troubleshoot this, let me know. I found a discussion where the order of the prefixes for names was slightly changed [3], i.e. *=- instead of =-* but I don't know if this matters at all or how to test it. Sorry for the text book, things like that really keep me digging.
