Regsvr32 strange behaviour = > Regsvr32 does not give any success or failure message

Question

I have an directShow filter: MyFilter.ax

When I try to register MyFilter.ax with Regsvr32 utility it gives NO error or any message(success or failure). But the filter is not registered.

Regsvr32 utility works fine for my other filters.

Why Regsvr32 deoes not give any sucess or failure message? How can I debug my Regsvr32 failure-sucess? Any alternative utility for registering directshow filter which may give meaningfull message?

Best Wishes

Update:

I install clean win7 OS on a virtual machine. Then try to register.Fail again without no message-response from regsvr32.

But then install again a clean win7 OS on virtual machine. Then make all updates. And after i make updates regsvr32 worked and install my filter....I do not know what cause regsvr32 fail and what kind of update fix it. Or is it really an update issue...

What can take place and exhibit the mentioned behavior is that somewhere in your filter you are in a dead loop, or infinite wait, so DLL's DllRegisterServer never returns. In this case, you will be able to see that each time you try regsvr32 Task Manager shows you one more regsvr32.exe running process, with or without CPU consumption.

If this is what you are having, you will want to attach with debugger and see where exactly you have dead loop there...
