^^^^^ 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....
After trying on and off for months/years, I have FINALLY got Generals and Zero Hour to work on Win7/10 from the Origin "Command and Conquer Ultimate Collection".
I found this thread while trying to Google an answer as to how to get it to work, and was somewhat shocked to find it is a years old issue, and still getting posts just a week ago :O
Anyway, here's how I got it to work... which may work for some others who still find this thread while searching for an answer:
1. Go to C: (or whatever drive your user home folder is on) --> Users --> <your user name> --> My Documents --> Command and Conquer Generals Data
2. In that folder, there should be an options.ini file; open it with notepad etc.
3. Find the line "Resolution = 800 600" (the default resolution) and change 800 600 to match your screen's resolution. Save.
4. Do the same with the options.ini file in the Command and Conquer Generals Zero Hour Data folder.
5. Generals and Zero Hour will now both run! (Well, they do for me now, after changing those settings).
