Problem

When trying to view documents in your Portable Case, QView, or QBlaze the Viewer is not showing anything other than a white screen and you see the following error in the logs.

Critical Unhandled Application Exception : Activation error occurred while trying to get instance of type IOixControl, key ""

 

Exception is: FileNotFoundException - The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Resolution

Verify these versions of Visual Studio C++ are installed in Control Panel:

Cause

There are several Visual Studio C++ redistributables needed for a Portable Case, QView, or QBlaze to work. This problem is presented when one of these is not installed or failed to install properly. Typically the 2013 x64 version is the one missing.
