Installer crashing attempting to install Titanium edition

[Falconz]

Hello all,

I've done numerous searches, I am stumped. I am on Windows 7 64 bit. Installation Method: mounted CD1 with Virtual CloneDrive.

Update**: So I know the files aren't corrupted. It installs on my laptop fine, just not my desktop. Only difference I can think of is my Laptop is a 1st gen i7, my desktop is a 2nd gen i7. Laptop is 4 core 8 thread, Desktop is 6 core 12 thread...

I've tried these:

-rechecked to make sure the installation files are pure and not corrupted.
-Run as administrator, Run with compatibility mode (XP SP2, SP3, Windows 98)
-Went over to C:\Program Files (x86)\Common Files\InstallShield\Professional and renamed RunTime to RuntimeOld
-Cleaned out all temporary files.

I keep getting the same message below...
