HTTP Error 500.19 Internal Server Error


Error 500.19 may be received when the PaperVision Enterprise ASP.NET application and Windows Server Update Services (WSUS) are installed on the same 64-bit web server.



This error is sometimes caused by a known conflict with WSUS and 32-bit applications. The issue is due to the fact that the WSUS installer will globally register a 64-bit compression scheme which is not compatible with some 32-bit applications. The resolution is to remove the offending compression scheme.


Use the following command on the server to remove the unwanted compression scheme. Note that this should not negatively impact either WSUS or the PaperVision Enterprise ASP.NET application.

%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']
