Dear Community,
I have the problem that I cannot uninstall your product.
I have already tried your remover and have also already tried the Control Panel
Without success. I have already tried all tips from the internet and it is NOT possible!
It always happens that I don't have enough rights although I am the system administrator.
I ask for quick help

With kind regards
Joshua Keggenhof
