Attached is a managed C++ dll that we have lost contact with the developer who created it for us. He put some code in this to make it stop working.
We need this converted to fully compilable source code. One the function called d needs to be decompiled. It is a simple de-encryption routine.
Deliverables should be compilable C++ source code in a Visual Studio project
After several minutes with a disassembler I found this:
'ldstr "Trial expired"' in your "d" function followed by an exception throwing (the reason it doesn't work anymore).
I can fix the dll for you for $30 if you are interested.
