CR for .Net 13.0.15 Does Not Display A Crystal Viewer In Windows 10 IIS

[Former Member]

I sell web apps for therapists developed using Visual Basic.Net 2012 as a website.

My databases are SQL Server databases.

I have the system installed in about a dozen customer locations, and all work perfectly except for my first Windows 10 Pro IIS 8.5 installation.

My database pages work perfectly, but my Crystal Reports pages do not display any report viewer at all.  It just displays a blank page.

This works perfectly on the development machine, and also on our Windows 2012 Server.  I have it installed on two or three IIS standalone machines, and ten or more Windows servers.

I have been developing with Crystal Reports since Version 8, and have more than 150 desktop (not web) systems installed at customer sites.

But my latest installation is a an ASP.Net web site on a Windows 10 Pro laptop.

The normal ASP.Net pages that update databases work perfectly.  But any pages that generate Crystal Reports do not display any Crystal Reports viewer - just a blank page.

I know that the Crystal Reports runtime is being invoked because I have one report with a bad datasource and it reports it.

I developed using 13.0.5, but on this machine I first installed the 13.0.5 64-bit runtime and it failed, so I then installed the 64-bit 13.0.15 runtime, but still no Crystal viewer.  I have also uninstalled and reinstalled 13.0.15.

Is there any explanation or solution?

I solved the problem.

I had added the "bobj" code to the web.config previously.

But I needed to remove the tilde from  <add key="ResourceUri" value="~/crystalreportviewers13" />

After removing it, all works fine in my Windows 10 deployment.
