Disk full message when installing program--NOT FULL

I am trying to install the program PCTV TV Center Pro 4.7 for my Pinnicle HD
Pro Stick TV tuner. Every time I try to install the program I get the
message that there is not enough disk space. I have 60 GB free. I do have
limited space on my D: drive, but that is for recovery, so I don't know why
that would matter. I have Vista home premium. I have installed the program
on windows XP computer with no difficulties.

I've tried the tech support at Pinnicle and I have received very little
assistance. They have told me to run the program as administrator and delete
my temp files. I've done both of those and neither worked.

Has anyone had a similar problem and/or know a solution?

 

Not a gaming question, but the program's installer probably is not used to
seeing large numbers, when you get to a certain number size if the program
isn't ready for that big of a number the right-most bit will cause the
program to think the number is "Negative".

In other words the program probably thinks you have a negative amount of
free space.

How to fix...

Call the software manufacturer (Pinnacle?), or go to their website and see
if there's a solution for the problem. They may have software you can
download online that'll work in place of the CD that came with the tuner
stick.

Good luck,
