E-Prime on Mac through Boot Camp with Windows 8.1 - Error 0x000003f3 "Unable to open DX Target

[Miguel Arce]

Hey everybody, 

I was wondering if anybody else has encountered this problem before. I've seen through the postings that several people have successfully installed E-Prime on a Macbook Pro through Boot Camp, so hopefully someone has encountered this error and knows how to go around it. 

I just installed my E-Prime on a MacBook Pro (Early 2011 model) that has Windows 8.1 installed through Boot Camp. Everything seemed to be running fine until I run one of my saved experiments. I get an error message stating "Unable to open DX Target" and "Unable to create DX11 Device. Use dxdiag to ensure your system has DX11 and hardware acceleration to feature level 11.0". I've checked with the dxdiag and I do not seem to have the required drivers, but I can't seem to find how to install them or update them. None of the updates I've installed work.

Hopefully someone can help. 

Thanks!

Miguel
