Cannot install software
If you have the problem that you cannot install GcMail Archive and you get an error message
Untreated exception: Error while creating the window handle.
Your antivirus program blocks 99% of the time the installation, or changing the license from one computer to another.
All you have to do is uninstall the antivirus program, “reboot” the computer so that the cache is cleared by the operating system, and then install GcMail Archive.
Start GcMail Archive and if everything is installed properly and you can activate the program, you can reinstall your AV program.
