When trying to view documents in QView or QBlaze the Viewer is not showing anything other than a white screen and you see the following error in the QView logs.
|Critical Unhandled Application Exception : Activation error occured while trying to get instance of type IOixControl, key ""|
|Exception is: FileNotFoundException - The specified module could not be found. (Exception from HRESULT: 0x8007007E)|
Verify these versions of Visual Studio C++ are installed in Control Panel:
Visual C++ Redistributable Packages for Visual Studio 2013 (both x64 and x86)
- Microsoft Visual C++ 2005 (both x64 and x86)
Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019
There are several Visual Studio C++ redistributables needed for 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.
