Hi,
We've seen this problem occasionally when someone puts the installation file on to a memory stick and tries to install from there. The installation program for the software (which is third-party) for some reason does not like doing that in some configurations. The solution is to copy the installation file to your hard drive and run the installation from there.
If the above doesn't work, please let me know either here or at our helpdesk at

ttfn,
Sherry
