-The challenge is you are running an 'old' program on a 'newer' computer.
-I had contacted Matrix in the past about this. I can run UCV, WITP, and AE on my WinXP but cannot get a useful screen centering to allow play on my Win10. My WITE consistently suddenly quits with a few minutes on my WinXP but runs on Win10. Was suggested Win7 might be best for my collection of games. My Win10 only function is Internet Browser, Matrix, and Vassal so if I every acquire a Win7, will convert it from Win7.
-Keep in mind the application dates. UCV(2002), WITP (2005), AE(2009), WITE(2009), WITW(2014). Also have WBTS(2008), PzC, ED-BTR(2009). I still play pbem DOS Pacific War and War in Russia as DOS runs natively on WinXP.
-DOSBOX emulation is out there but I have found it inferior in using my full screen versus an OS than runs the game natively. Also I have never figured out how to get the mac version to run as cannot defiend a driveC as none exists on a Mac. The DOSBOX help and email never respond to my queries.

Run the game in windowed mode. For running the game in windowed mode please do the following:
Open the game installation folder and find a file named "War in the Pacific Admiral Edition.exe". Click with your right mouse button over it and select "Send to > Desktop (create a shortcut)". This will create a new shortcut for the game.
Click with the right mouse button on the new shortcut and select Properties. Add the -w -px1920 -py1080 switches in the end of the "Target:" box line (check the attached screenshot.) If the installation folder is the default one, it should look like this:
"C:\Matrix Games\War in the Pacific Admiral's Edition\War in the Pacific Admiral Edition.exe" -w -px1920 -py1080
After adding the switch click on the "Apply" and "OK" button. Start the game by using this desktop shortcut.
