Disk Warrior refuses to install on any mac computer

As a last attempt, I decided to retry installing disk warrior again. Copied Disk Warrior once again to the utilities folder after complaining to Alsoft over a week ago. Ejected the DiskWarrior CD. Ran the program and it ran without giving any errors.

I think there must be some kind of copy protection on the software which went amuck and prevents installation on more than one computer even though I cancelled out of installing it on the first attempt.
Has anyone had this issue with Disk Warrior refusing to install on any mac computer because of an alleged corrupted prefs file that doesn't exist?

Weird thing is... never had it installed on this computer. Ran the software installer and it kept crashing. Tried installing it on other computers... same issue.
Obviously a bug in the installer or copy protection.
Who knows why its such a pain to install. Sure doesn't speak well for it supposedly being a good disk fixer.
Anyways since 4.1 is for both intel and power pc it was surprising that it wouldn't install on either since neither had any previous install. Alsoft says I must have installed a shortcut instead of the actual program... funny... is that how their installer works?
The only thing I did different the second time was to eject the cd after copying the program to utilities. Then it suddenly decided to work. Weird..

It says there is a corrupted prefs file for Disk Warrior. Funny since there was no previous install and no such file exists... please explain how that could be?

After paying $136 I do have a right to rant for poorly designed software that won't install since it means I'm out a lot of money for something that won't work. That is unless Alsoft wants to provide a refund... they didn't respond after I asked for a refund to return the software so I'll take that as a, "NO!" Buyer beware!

I do live in Canada. We are still paying more for software than in the US. I have version 4.1 and it is for intel and power pc (neither installation worked for a week).

As stated, after trying a week later and ejecting the CD before installing into my utilities folder.... suddenly the installation worked. Maybe they should have a line that says eject CD first before installing if that is an issue?

Still no idea why it wouldn't install but obviously other people are going to run into similar problems at some point in time. For a product that has a lot of hype about it being so great, obviously there are some bugs to work out.
