How to resolve allInOne.js errors?

We're upgrading to CrystalReports 13 and .Net 4.5 in Visual Studio 2013 using SP9. Most of it was a breeze. The only thing that doesn't work is the integrated view in our website.

The knowlegde base article: Redirecting...

and the thread Javascript error in allInOne.js do not resolve the issue we're having.

The issue is that that the viewer is not visible. This is caused by errors (below the errors reported in Chrome, in IE it is something similar).

What am I missing?

The crystalreportviewers13 is available in C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13

However, while debugging using IIS expres (in VS2013) the only way to get past the famous BOBJ issue is to copy the directory locally. Any tips?

Thanks.

Best regards,

Michiel
