Hi,
I am running a build on windows 7 64 bit environment. One of the action item is registering a 32 bit dll.
That is failing with error code 5. I am working with final builder 6.0
Any help here greatly appreciated.
Regards,
Lakshmi

I just tried it here and it worked find with a simple activex dll and it worked find. All it does is run regsvr32. Can you try running regsvr32 from the command line and see what happens?

My situation is exactly same like in the below post
[https://www.finalbuilder.com/forums/finalbuilder/general-discussion/regsvr32-on-win7/#16700](https://www.finalbuilder.com/forums/finalbuilder/general-discussion/regsvr32-on-win7/#16700)
The difference is i am using finalbuilder 6.0.
and O.S. is Windows 7 64bit.
