^^^^^ This solved the problem for me on a Windows 7 Ultimate x64 machine ^^^^^
There were 2x copies "dbghelp.dll" in my Zero Hour folder, nuking both fixed it.
God help anyone that uses EA chat help....
I tried all of the previous solutions here (and many others) without success.
*** SOLUTION ***
Here is what worked: https://cncnz.com/features/technical-support-help-guides/installing-command-conquer-generals/
I've had Generals & Generals: ZH working on my Win 7, 64-bit system since they were installed a few years ago from Origin. Not the Ultimate Collection. Just the package with Generals and G: Zero Hour.
Yesterday I was installing Star Wars Battlefront 2 and found that my ripe old Radeon 15.7 drivers needed to be updated for the new (er) game to run. I did so and it ran fine. Later this same day, I went back to General: ZH,. I was in the middle of a challenge and wanted to finish. Only now I'm immediately rejected by this DX error!!! After a frustrating hour of trying different things like reinstalling DX (11?), the latest I could find from MS, and deleting those DBGHELP.DLL files I read about, I've still had no luck.
The only thing that makes sense to me is for some reason with the new Radeon drivers (latest version, 20.11.2), either G:ZH or DX now thinks the drivers/card isn't compatible with the game. Considering I was just playing it YESTERDAY, that's obviously wrong. No idea what else to try, other than maybe see if I can switch back to the several year old version of AMD drivers.
Also for whatever reason, Generals works fine, though I didn't even try it before deleting the DBGHELP.DLL files. Only Generals: Zero Hour is giving the the problem.
