Suppose some author has enforced his Windows application to be single instance. Is there any way to make multiple instance of this application (aside from running inside a virtual machine or requesting the author to rewrite the app)?
If there is a readymade tool, I would like to know it. (I have tried sandboxie and Altiris SVS without luck).
If there is nothing out there, I want to program a tool/hack that will let me do this. I am looking for pointers where to start - what will be involved, what skills would be needed. I have moderate programming skills in C and Java.
If this cannot be done, please explain why.
EDIT: I know its a bad idea but I still need to do it (for various reasons). I want a generic way that works for any application and does not introduce errors.
