I am running crystal report for .NET framework v. 13.0.15.1850 on Windows 2012 R2 server. After the following recent Windows updates, crystal reports no longer shows on web pages served by this server. Instead, I get a white screen, with no errors. After rolling back these updates, Crystal reports works again. I will have to disable updates if I can't find a solution to this.
Updates (note that after I rolled them back Windows continues to try to install them):
