Csolis,

No, this behavior is definately not normal. I have a setup
similar to yours, with no problem, so at least we know it's
possible for both to coexist (although frankly, comparing
VideoFactory to VideoWave is like comparing a Ford Mustang
to a tricycle). Anyway, the first thing I'd recommend you
do is completely empty out your Windows temp directory
(using disk cleanup, probably in your accesories menu in
Windows).

Sometimes, programs try to access file from the temp
directory, like "setup.exe" for example. The program,
wanting to install a component, goes to the temp directory,
and finds "setup", and runs it, hoping to install the
plugin. However, "setup" wasn't the "setup" for the plugin.
Another program launches instead, since their names are the
same. Emptying your temp directory ends this confusion,
since only one program will have one name instead of
getting mixed up with someone else.

Yeah, I butchered that explanation. I'm tired, so big deal.
Anyway, just empty your temp directory and see if that
helps. If not, reply back here.

Good luck,
Nick LaMartina
