I am receiving this error again and again followed the below instructions , any other ideas? Please run Windows Update to ensure that your system is up to date then check that you have temporarily disabled all system protection then attempt to run R46 If the same error occurs run the Visual C++ 2015 Redistributable setup located in C:\Program Files\CAST Software\WYSIWYG Release xx\Bin64\vcredist14_0_x64. [where xx is the wysiwyg release number] Once that is complete restart your system open R46 and let me know if you encounter the error. If you do please send me a screen shot of the message received when executing Visual C++ 2015 Redistributable setup (there will be a log file you can click on in the dialog) and the Windows Help>About screen [type search in the windows search bar]
