I've a copy of 'PictureThis!' and am triying to install 'Showoff'. I'm using Windows 8. A message says "E:\media\products\showoff\setup.exe cannot run due to incompatibility with 64-bit versions of Windows. Contact vendor to ask if a 64-bit Windows compatible version is available."
You receive that error because the application was designed to work in Windows 8. The compatibility is limited to these versions of Windows only: Windows 95, 98, NT and XP.
Hmm.. maybe there is a 64-bit version of 'PictureThis!.
