To use the Content Analyzer on Microsoft Windows, you need to install Microsoft Visual C++.
We've included it in the Content Analyzer installer. When you run the Content Analyzer installation wizard you might see a Microsoft Visual C++ window. Agree to the terms and click 'Install'.
On some computers, the installation of Microsoft Visual C++ 2015 seems to hang and can take up to 1 hour to install. We've observed this scenario in particular on computers running Microsoft Windows 8.1.
At the moment we can't find a rhyme or reason for this issue but we'll try to put it to rest in a future release. Your only alternative currently is to use an alternative OS such as Windows 7 or Windows 10.
