Hi and a happy new Year,
I'm using ExcelDNA 0.30 stable, Excel 2010 (32Bit) on a Win7 (64Bit) machine.
I've wrote an Add-In class in VB.NET (VSExpress 2012), which inherits ExcelRibbon.
Everything's works fine until the mid of last December. Probably the date doesn't matter ;-)
Now, I can't see the Ribbon and contextmenues anymore.
Excel says nothing, except some "ExcelDna.Loader.DnaMarshalException" and "System.Reflection.TargetInvocationException" in mscorlib.dll and ExcelDna.Integration.
I've testet some older versions of my Add-In but I get the same behaviour. I'm wondering.
I tried to start a new Add-In Project and installed the ExcelDNA through the NuGet Packetmanager and with a minimal XML-output from the overridden GetCustomUI function.
The same result. No Ribbon appears. :-(
So, I'm a little bit despaired and I hope, some one can help me, please.
Thank you very much.
P.S.: Sorry for my terrible English.
The Ribbon-Class is ComVisible, I'm compiling for x86 and the NEW procedure is invoked.
