InstallAware

As I want to install X6 and have limited space available I want to uninstall X5 before.
I tried several times but It hangs several minutes at the message "Unregistering InstallAware Add-In for VisualStudio 2015".
Then it finishes with the message "InstallAware Installation failed "General Setup failure". Please check your Settings and try again".

I checked the Settings used repair etc. without any success uninstalling.

How to proceed?

Dear Horst,

this may be due a system corruption.

I suggest you to try with the following tool.

hope this helps you.

Dear Francesco,
sorry did not work.
InstallAware is not in the list of programs to be uninstalled.
Do you have a GUID to enter in the "Not listed" field?
