Far shot, but you can try Wine!
Go to YaST's software management tool, and make sure wine is installed. Then run
winesetup to get wine set up properly (do
NOT run winesetup as
root!)
After all that is done, try
wine <windows_partition_mount_point>/<program_installation_dir>/<executable_file.exe>
This should look something like
wine "/windows/C/Program Files/grabit/grabit.exe" (or similar) WITH quotes
