COM DLL registration failed

Hi,

I have library of COM components. I am using VS2005 SP1 for
development. Few days back everything was working fine. Suddenly (may
be after windows security update i guess) my DLL registration is
failing when i build it from VS solution. If i register them manually
using regsvr32 then they are successfully registering. Due to this
problem project is failing on build machine.



I am getting following error while building my solution under VS2005:

error PRJ0050: Failed to register output. Please ensure you have the
appropriate permissions to modify the registry.

Any idea what is causing it?

Thanks in advance.
