When uploading a PDF to a share pod in a meeting on an on-premise server version 9.1.2b on some installations the file cannot be converted.
In the access.log you get a message like this:
“Internal error ‘Pdf to swf conversion failed with return code -1073741515′ occured”
If you run into this problem please verify that you have the “Microsoft Visual C++ 2010 Redistributable Package (x86)” installed on your server.
If it is not installed, install it from here: http://www.microsoft.com/en-us/download/details.aspx?id=5555
Make sure to install the 32bit version even if you have a 64bit OS.
If the file still does not convert after successful upload to a meeting, please contact support.
