Package management initialization failed. When launching Visual Studio 2017 (15.7.2) - visual-studio

Question

After installing VS2017 Community ver. 15.7.2 on Win 7 64-bit, following error was found when launching VS2017 with or without admin privilage:
Package management initialization failed.
You can get more information by examining the file:
C:\Users\NAME\Appdata\Roaming\Microsoft\VisualStudio\15.0_5024a39e\ActivityLog.xml
These are the errors found in ActivityLog.xml file:
Infos: Could not find ConfigurationChanged timestamp.
Error: merging configuration file C:\Users\\AppData\Local\Microsoft\VisualStudio\15.0_5024a39e\devenv.exe.config

Tried to install VS2017 Enterprise as well as the VS2017 Community 15.6.7 and got the same errors.
There is a similar problem answered here but it doesn't work for me.
Any input is appreciated

Answer 1

I had the same problem, i solve that doing this
Uninstall Visual Studio 2017 and other Visual Studios
Delete C:\ProgramData\Microsoft\VisualStudio
Uninstall any Visual C++
Look for any Visual Studio Key on the Regedit and delete
Delete C:\Users\UserName\Documents\Visual Studio 2017 (Backup your projects)
Delete C:\Users\UserName\AppData\Local\Microsoft\Visual Studio\15.##
Update your Windows and restart your pc
Install Visual Studio 2017 again
Try to open, and one error apears
Copy the devenv.exe.config file locate in the root of the IdE to
C:\Users\UserName\AppData\Local\Microsoft\Visual Studio\15.##
Try to open again
Try to open in safe mode
Try devenv.exe /resetSettings
Try to repair Visual Studio Again
For me works :) !
