I've tried everything, yet i still can't get it to run.

what os & machine specs?

OS: Windows 10 Home
Specs:
CPU: Intel Core i7-9750H
GPU: GeForce GTX 1660Ti
RAM: 16GB DDR4

does it show an error screen or something else when it doesn't launch?

A few things I've tried with various games and it helped:

- Make sure in your security settings in Windows that DEP is turned off for non-native windows processes.
This prevented me from launching Blood II and Unreal Gold.
- If you have a 120Hz monitor (or anything above 60Hz), try downloading CRU (Custom Resolution Utility) and add a 60Hz profile to your monitor, before that I couldn't run Lego Star Wars: Complete Saga and Deus Ex Invisible War would hang at the loading screen when starting the game proper (after choosing my character's face and difficulty).

Also try the widescreen fix, maybe the game dies trying to set the resolution.

I'd give the widescreen fix a try too:

I didn't have any problems running the game before I applied that, but the higher resolution looks pretty good. I have an AMD GPU but I'll give it a try on the kids computer with an Nvidia to see if it runs.

Runs fine on the kids Nvidia.

HUGE THANKS MAN! Finally after spending HOURS trying other stuff,I decided to change refresh rate to 60 Hz using CRU and that solved the problem of the game not launching.Now I can finally play more than one year from when I purchased it.

Glad I could help, have fun!
