i have tried the tubinator regedit trick and yfb works with keygen so their is no obvious solution.thats why i am asking for help.

i have posted this problem on coding forums and they tell me about programming solutions? about which i have no idea

so any other ideas?

also the .net framework is exact as required.

Any suggestion about which DLL files can help?

Thank you everyone for taking interest in my problem.
