Whenever i start NWBC 5.0 it crashes immediately.

I checked the trace files and I get this message:

##########  Log continued from previous file C:\Users\Shane_2\AppData\Local\SAP\NWBC\Traces\NWBC.exe.#2852.0.log  ##########

NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See for more information.

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?

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,
