TouchKeyboardUI.xaml.cs works only for 32 bit OS or 64 bit process

[trivalik]

Environment.SpecialFolder.CommonProgramFiles in TouchKeyboardUI.xaml.cs give back wrong value if 32 bit process on 64 bit OS is running. TipTap.exe could not be startet then.

Solution could be:

Environment.GetEnvironmentVariable("CommonProgramW6432") + @"\Microsoft Shared\ink\TabTip.exe")
