Some years ago years ago I bought a new gaming rig and never got FS2004 installed on it. Moving all the add-ons to the new rig as well as recreating years of tweaking seemed as a insurmountable task for a PC dummy like yours truly.
I tried once, only to get an error message from disk 4 that a specific file was unreadable and thus the installation would be aborted. After some serious cleaning and polishing of disk 4 I still got the error and gave up
Instead - meant as an interim solution - I moved to the 'Dark Side' of FPS' like COD, BF3 and BF4. And has been there ever since
Lately I have considered to give FS2004 a go. Either by somehow 'fixing' disk 4 or by purchasing FS2004 as used from someone, if still possible
And I thought I'd go here and see if the old girl is still alive and kicking. And I believe that the conclusion must be: Yes (That's truly amazing :-)
However, I also see that with WIN10 on my rig, the plan may be grounded thoroughly and for good :-(
