GroupWise 2012 SP2 Windows Client - Windows 8.1 x64

I have installed GroupWise 2012 SP2 Windows Client on a Windows 8.1 x64 laptop.
I can run GW for the first time, and it works fine.
When I close GW, and then reopen it I get the following error:

GroupWise is not properly installed. The GroupWise components could not be initialized. Please run GroupWise setup, or contact your system administrator.

A reboot will not fix the problem. If I completely remove GW and then reinstall it works fine, however once you close GW and then reopen it, you get the above message again.

Does anyone have any ideas?

Thank to everyone in advance.
