Hi pauljorr,

Could you post your dxdiag (system specs) and log files? Also, follow the instructions in this link and post your Debugging logs as well.

Hi pauljorr,

what you’re seeing is a general error that can occur with any install process. Make sure you have the latest DirectX and .NET Framework. You may also need to reinstall these if updating does not fix the solution.
