The people at Python may know Python quite well, but when it comes to packaging their product, nearly 100% of their installers have been botched in some way…and the 3.6.150.0 is no different. I ran into multiple issues when trying to deploy this. See below.
#1 – When deployed in the System Account, the app doesn’t appear in Programs and Features.
#2 – When installed in the System Account, the GUID {37a4e38b-baf7-4500-97f1-0f7c51d9a395} is installed in the wrong location.
#3 – The uninstall brings up the wrong window (their reg keys are wrong).
#4 – Once I modified the uninstaller to remove the app, not all files were removed.
#5 – Once I modified the uninstaller to remove the app, not all reg keys were removed.
Advice to Python, hire an actual packager. The 2.7.13150 MSI was also busted. I ended up just performing a capture/snapshot of the MSI install. For those looking to deploy the MSI and can’t, hit me up. I’ll send you the EXE I created from the snapshot. See bottom for a screenshot of 2.7.13150.
The Fix
So, to fix this mess, first I did the install with the options I wanted (scripted of course):
* I add the GUID app to c:\ProgramData\Package Cache
* Point the reg keys to the new package cache path
* Create a simple removal tool.
The Script

So, after fixing these reg keys, copying the app guid folder to the proper place, and creating a removal tool, I finally got everything working.
