Alright. I am making a note about this but first let me get to the Minecraft issue, then please remind me about this one.

This isn't only a Python issue, i cannot install any MSI installers neither Google Chrome.

An Installation with verbose logging showed the following error:

DEBUG: Error 2203: Database: C:\Windows\Installer\inprogressinstallinfo.ipi. Cannot open database file. System error -2147287037

I tried to create this file manually in the Sandbox and it worked, but it got deleted.

Right, that's the symptom. Actually the problem is a missing folder
C:\Windows\System32\config\systemprofile\AppData\Local\Temp
in which the Windows Installer service is trying to create a temp file.

I'm not sure why this works outside the sandbox but the next beta
build will create this folder in the sandbox and that fixes the problem.

Please check version 4.05.01.

Python* tested.
Windows 7 (32-bit) passed.
Windows 8 (32-bit) passed.
Windows 8 (64-bit) passed.

This problem also affected installing Copy.com (ver 1.33.0486), a cloud app like Dropbox.

Upgrading to beta 4.05.02 allowed me to install the program.
