Entry point not found

[straubz]

Gday people
Hoping someone can help me out
Purchased protoolsexpress today and cant get it to load. Ive attached a png of the error file im getting.
I install the software (version 10) and on load it says no hardware found. So i install the Avid HD drivers then get the no entry point error.
If i uninstall software & drivers do a fresh install of software only i dont get the error. Thats telling me its a driver problem but i cant nut it out.
Ive uninstalled and reinstalled. Drivers first then software, on external drive and boot drive. Done everything mentioned on this forum and others but no joy.
Running win8.1 on a i7 3.4ghz with 16G RAM
I also tried installing on a laptop running win7 but no joy there either.

Cheers
