Do you have full administration rights for the user when you try to install?

 

Have you tried to deinstall WATCHOUT 6.1.5 manually through the Windows settings "Programs and Features" part?

[truls]

Yes, I have full administration rights.

 

And  I haven't tried to uninstall WATCHOUT 6.1.5 yet. I just want to know if it is a bug in the installation file to 6.2.

[Vollmers]

From all I know, and I just upgraded recently with the same versions, it’s always a good idea to uninstall the old version. You really don’t gain anything from not doing it.
