Problem: Customer reported that if they attempt to run GWmerge in demo mode on Windows Vista, it works fine. Once a full "gmwreg.dat" file is added, GWmerge reports "You are not properly licensed" error when he attempts to run the program.
Cause: This is a Windows Vista "Security" feature.
Resolution: Right-click the gwmerge.exe file, go to "Properties" > "Advanced" and choose "Always Run as Administrator".
Applies to: GWMerge 2.8, Windows Vista
