Whenever I start up (new OR exixting) a small window pops up advising me to reset SCREEN RESOLUTION to 1980 x 1020. It's already at that, and I cannot access the window to say so, or tell it not to adsk me that again. Is there a solution to this?
I'm curious, because in >5 years of playing Civ3Complete, I've never seen this: Is this pop-up generated by Windows, or by the game itself?
If it's a Windows(10?) notification, you may need to go into your "display-settings" menu to check that Windows
is actually still using the correct resolution for your monitor (because it's
possible that e.g. a recent update may have reset it without notifying you). If it's a Civ3 pop-up, then the following information about my setup may help you narrow down/solve your problem:
I have a download-version of C3C from GamersGate, first installed on an old WinXP laptop with a 1280*800 screen, and later also on a Win8.1 desktop using (initially) a 1920*1080 monitor, and (now) a 1600*1200 monitor (with the widescreen-monitor demoted to secondary).
For WinXP, the game is in the default installation location in
C:/ProgramFiles/Firaxis/...
When I installed under Win8.1, I deliberately set an alternative installation path,
D:/Games/Civ3/, both to avoid problems with VirtualStorage (of save-files etc.), and also because my D-drive is substantially larger (HDD, 1 TB) than than my C-drive (SSD, 250 GB).
To prevent distortion of the preset 4:3 screens (for game-setup, advisors, etc.) while playing on widescreen, I inserted the line 'KeepRes=1' at the end of the
conquests.ini file (in both installations).
When I switched to using the 1600*1200 monitor as my primary on the Win8.1 box, I
replaced the 'KeepRes' line with 'VideoMode=1600' (this appeared to be necessary, because otherwise the game-screen spilled over onto the secondary).
