For people who try "Run as Admin" or who tinker around with "Compatibility" settings and still cannot get this game to run on Windows 10 (as was the case with me) here was my solution.
1) Download
DXWnd from
here.
2) Unzip the contents of the downloaded
.RAR to any folder you wish.
3) Inside that folder you will see
dxwnd.exe. Run it.
4) Once the program is running right click in the window and select
Add 5) Fill in the
Name field with any identifier you want.
(e.g.
Caesar 3)
6) Fill in the
Path field with the location of your Caesar 3 executable file
(e.g.
C:\Program Files (x86)\GalaxyClient\Games\Caesar 3\c3.exe)
7) Modify the
Window Initial Position and Size field to suit your fancy.
(e.g.
X=0 Y=0 w=1366 h=768)
8) Optionally select the
Desktop Center setting. Not required, but it looks nice.
9) Make sure
Run In Window setting is checked.
10) Click
OK That's it. Try running the game from within the dxwnd client, from the shortcut on your desktop, or through the GOGGalaxy client itself to see if its working.
P.S. If you are experiencing looping music during game play download
IndirectSound from
here. It is a small
.zip file which contains a file called
dsound.dll. Copy this
dsound.dll file into your game's installation folder (e.g.
C:\Program Files (x86)\GalaxyClient\Games\Caesar 3\c3.exe) and it should resolve the issue.
