Why can't some applications be selected or executed from the VAIO Mode Switch application in the 64-bit version of the Windows Vista operating system?
Some applications cannot be selected or executed from the VAIO Mode Switch application in the 64-bit version of the Windows Vista operating system.
This is a limitation of the VAIO Mode Switch application. Applications that run in both the native 64-bit environment and the 32-bit emulator (WoW64) should work correctly with the VAIO Mode Switch application. Programs that only run in one or the other environment may not work properly.
