Installation Error Due to Failed PIA Deployment

PROBLEM

You cannot complete the installation of Test Studio and receive an InstallPIA error. Rerun the install with logging enabled and confirm the error message in the log is similar to this:

 

Action start 15:15:37: InstallPIA.
MSI (c) (94:44) [15:15:37:513]: Invoking remote custom action. DLL: C:\Users\[UserName]\AppData\Local\Temp\6\MSIF64C.tmp, Entrypoint: InstallPIA 
Action ended 15:15:38: InstallPIA. Return value 3.
DEBUG: Error 2896:  Executing action InstallPIA failed.
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2896. The arguments are: InstallPIA

SOLUTION

Install PIA (Microsoft Primary Interoperability Assemblies 2005). Test Studio relies on the old Office 2005 PIA assemblies. Even if you have a later version of Microsoft Office installed, the required assemblies linked below will install correctly with your existing Office installation.
