NWBC 5.0 Crashing

[shane_kelly2]

Whenever i start NWBC 5.0 it crashes immediately.

I checked the trace files and I get this message:

I checked this thread () and verified I am running .NET framwork 4.5.1 (Which meets the minimum requirements)

.NET version is 378675 = .NET Framework 4.5.1 installed with Windows 8.1

Any ideas?

Dear All,

c# - .net local assembly load failed with CAS policy - Stack Overflow

Here is a possible cause of this issue. Please check on it.

Hi Shane,

I have the same error and have opened an OSS on it, but haven't gotten very far on that.

But you can use NWBCcore.exe instead, this works.

Hi,I also faced this issue.

I used the workaround that Jakob gave(putting NWBCCore.exe in the shortcut)

After this I openend the NWBC, and closed it again.
I changed the entry in the shortcut "NWBCCore.exe"back to "NWBC.exe"

It now suddenly works.

Hope this helps,

Menno
