I am to VB. I created setup files for my application using package and deployment wizard. We the system is installed in different computers it gives different errors. most of them are "unable to register dll files". The strange thing is nevertheless when you ignore the errors and the installation is completed, the system runs properly. How can I avoid this problem and make my setup files register all the needed dlls and avoid to prompt the error message when these files exists and no further installation are needed.

What is the OS?
I suspect that you are running into access violations, where the person doing the installation does not have the necessary permission level to modify the Registry.

You say “Different errors.” what are the others?

The os is windows xp. when installing the system in my office it gave some errors. In my team's leader computer it gave other set of errors. and a third set (and biggerst number) of errors when I installed in my computer at home. If you give me your email I can attach screen dumps of the errors.

I would just as soon [u]not</u> get screenshots.

Can you just say what the message was (don't bother giving the error number...)?

This is the first error as an example
REGSVR:DLLRegisterServer failed on ‘C:\WINDOWS\System32\Oleaut32.dll’
-2147024891 : Access is denied

This is the first error as an example
REGSVR:DLLRegisterServer failed on ‘C:\WINDOWS\System32\Oleaut32.dll’
-2147024891 : Access is denied
Then the following errors comes
Unable to register library ‘C:\WINDOWS\System32\Oleaut32.dll’: The operation completed successfully
