CLSID error 80040154

I’ve got a c# app that I’ve developed, and am now trying to compile on my new system I’ve had a few problems, biggest one being at the line: ‘NotesSession session = new NotesSession();’ ….I’m sure it compiled ok on my last!

I get the error….CLSID {blahblah} failed with error 80040154.

Turns out that Visual studio was compiling for “Any CPU”, this needs changing to x86, as the notes COM objects don’t do the x64 shizzle. All makes sense now, as new laptop is 64-bit!!

App now works and I’m a bit happier!
