I attempted to install S&T 2013 on my Surface Pro last night. The installation was uneventful and the installer reported success, but the app would not run, reporting a "missing .dll" error.
Searched the MS website for solutions and installed first the x64 version of the C++ redistributable and then the x86 version, both without success. The app continued to report an error, this time related to permissions.
Again searched the MS website but found conflicting reports that S&T 2013 is NOT on the compatibility list for Windows 8 (???) and reports that S&T was installed and working! Also found a fix for the permissions problem that was, itself, problematic. At that point, I uninstalled S&T.
