Good day,
I cannot answer your question directly, but I can tell you that Win 8 has a lot of issues running some programs and/or using older device drivers. Win 8 has changed their security model quite substantially and as a consequence Win 8 will simply not allow some programs to operate correctly and/or prevent some device drivers from loading. In Win 7 and prior the user was given a security message (dialog) warning them of potential issues, but the user could proceed if they wished. This option has been completely removed from Win 8 and so the user is under the mercy of Win 8's decision. There is a mechanism to disable this "strict" security policy, but it is only temporary and the system will revert back after the next reboot.
Lastly, older and/or legacy programs that would run on Win 7 with XP mode are totally out of luck as their is currently no "XP Mode" add-on to Win 8. Hopefully the commercial industry will push back on Microsoft so as to "force" them to make some changes...
Anyway, like I said this is just a heads up. Ensure you test, test, and test with Win 8 before you deploy.
Cheers,
Sam
