I am trying to install a new program. When the install is trying to "register support components" I get an error message that states "the file Windows/System/RegSvr32.exe cannot be found."

After researching a bit I now know that this is a file on the Windows 98 CD, and that it has something to do with Active X.

That is not much information! What is the install trying to do? Why don't I have that file? And, if I need it, will re-installing Windows take care of the problem?
