Error when installing a DLL using Install SHield.

[baseballgem]

I created an install program for a VFP8.0 single threaded DLL using install shield.
Now the Install tests fine. It even installs fine on my computer and 2 others we have in house.
But on this one particular computer it begins the install and the progress bar gets about 80% thru when a window pops up saying..

Error 1904.Module C:\ProgramFiles\etc\validlicense.DLL failed to register. HRESULT. Contact your support personel.

Even when logging in with Admin rights we still get errors.
Again, it happens on only a few of the office machines.
Does anyone have experience with this?

Anti-virus software?

There is resident anti-virus software installed on all the office computers equally. Could the existence of some anti-virus software trigger this error?

One way to find out...disable the anti-virus application and give it a try.

Sounds like a common issue not specifically related to any program other than the OS.
