Subsequent runs fail

[leosenko]

First run seemed to have worked but left things hanging (sql server, redistributables etc.). I (probably wrongly and should have run the tool again) removed all these but this resulted in VS 2015 reappering in add/remove programs and again impossible to uninstall. Any subsequent run of this tool results in crash of the application, if I run it from command line, I get:
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or ass
embly 'Setup.VS.ConfigurationManager, Version=1.0.0.0, Culture=neutral, PublicKe
yToken=null' or one of its dependencies. The system cannot find the file specifi
ed.
at Microsoft.VS.Uninstaller.Program.Main(String[] args)

using the depends utility, i get:

I removed .NET 4 completely and cleanly installed and I also installed VS redist 2008, 2010, 2015.
I admit, there is a more serious problem with the computer and that is actually why I could not iuninstall VS 2015 in the first place
