PB COM registration issue on Windows 7 machine

Hi,

I have COM component generated using PowerBuilder 11.2  (This COM component used by the .net application to interact DB). When I registered the dll on my and colleague machine (PB installed on our machine) it is registered successfully. When I tried to install it on a different (Non Powerbuilder installed machine), it is not registering the dll. I have supporting dlls copied on that machine

I have updated path to the dlls directory. Registering the dlls not working.

Is there any supporting dll should be registered? Or any dlls i am missing to copy it

Note: I have used regsvr32 under the sysWOW64 folder to register this dll since its 32-bit.

Thanks,

Senthil
