install on windows

[Bart Pietercil]

ok I think I found the problem.

Problem was gone after restarting the machine.
No before trying this , I installed Valentina rb in a second location.
How do I uninstall v4rb because now I get duplicate function errors  
(probably because I installed twice)

So the questions is: How do I uninstall v4rb?

no uninstall option in the installer ?
no uninstall in remove software control panel ?

So How ?

TIA
