Premiere Pro CS3 (Version 3.0) will not start following upgrade to Windows 8-- rest of CS3 is fine

Question

Recently upgraded from Windows 7 Ultimate to Windows 8 Pro;
next time I tried to open Premiere Pro 3.0 (Adobe Master Collection CS3), splash screen scrolled normally through files being loaded until "SolidComposite.AEX", where it white-screened & crashed. 
Tried removing that file, it crashed on the next ".AEX" file; removed all ".AEX" files, it began crashing on ".dll" files;
kept removing THEM, just for the heck of it, until the software loader couldn't even start.
I popped in the CS3 disc to repair the installation-- on the entire suite, for good measure;
re-booted & started Premiere-- crashed at the exact same point.
Uninstalled and then re-installed Premiere-- the entire suite in fact, since there are so many common processes;
couple of hours later, re-booted & started Premiere-- same exact thing at the same exact point.
I found this same problem in at least a half-dozen threads, going back to '07--
and several of them even mentioned the same exact file as the trigger for the crash!
Unfortunately, not one of those threads has ever ended with an accurate diagnosis of the problem,
nor a solution more insightful than reinstalling both the CS & the OS.
I don't want to abandon Windows 8...
but on the other hand, I just can't afford to pony up another grand to upgrade the CS Suite again, either...
Besides: CS3 is everything I need, and it has worked wo well for so long--
even now, Premiere Pro is the only software in the suite with a problem!!
(I used Photoshop to create the above screencap)
So I'm hoping against hope that one of you techno-gurus may have come across this ITRW--
and actually SOLVED IT!!

Thanks for your prompt reply, John-- and for NOT simply advising me to spend my kid's tuition on more of your company's products...
Actually, I had tried the "Run as Administrator" option already, having found it in one of those other threads;
there was no change in the sequence described above.
I decided to try another possible solution which I read about in one of those other threads: opening Premiere from a different account. 
Incredibly, it WORKED-- sort of...
I got a couple of popups advising me that missing codecs had to be installed-- and upon completion, Premiere opened!
Here's an interesting note: the last file to load was still "SolidComposite.AEX"-- and the "White Screen" I kept seeing was Premiere opening normally.  The next thing that displayed was the normal  dialog box "Open/New Project"-- I entered a new project name, and Premiere started normally. I even added a few video files as a test... all opened normally.
I returned to the Admin account to see if the fix was in here, too;
but clearly the war wasn't over, over here...
It now appears that some personal setting in the Admin account is causing Premiere to close itself;
I've been reading about the layered security measures embedded into Windows 8-- I'm suspecting the conflict lies there...
I ran the Windows Troubleshooter & got this:
both MS & Adobe confirm that CS3 is fully compatible--here's my sytem info:
Since I seem to have established a fall-back position that lets me use Premiere, my crisis becomes a mere conundrum;
but I know this is gonna gnaw at me anyway, & I'm hoping that this new information might suggest further troubleshooting options to someone who understands the Adobe software and/or the Windows software better than I do!
Speaking as someone who has found many solutions on forums like this over the years, I assure you:
for every person whose post you reply to, there are many more whom you will never know you have helped!!!
