Error while Registering DLL

I have this vb web application , which I wanted to deploy in one of our deployment servers.

I built a package(For support file) using package and deployment wizard, and ran the setup.exe on the deployment server .

Following is what happened
Error while registering dll
Error number 0x80004005
logs says "DllRegisterserver() returns failure"

Any suggestions on this will be helpfull
Thx in advance

this looks like a permissions failure to me. Have a go at manually registering the dll using regsvr32. If you already have a dll of the same name registered, then try unregistering it first using the command above with the /U option.

No I did try regsvr32.dll manually, result was the same (error number 0x80004005).

Infact I tried this option, before creating the package

Is there any thing else any one can think of.

Thx in advance

Make sure the correct version of ATL.DLL exists on the target system ?
