Jane's Fleet Command uses a InstallShield Wizard that doesn't even work in Windows XP. It just says the executable is not Win32. As soon as I execute it in Windows 98SE it launches and allows me to install the game. Can anyone explain what's going on? Some special PE header?

It's possibly it's a 16bit executable and NTVDM is broken on your system. Are you able to run DOS games in the command prompt in XP on your system?
If it's just the setup executable you can post it here.

I tested it on Windows 11 first. I even had NTVDMx64 as well as OTVDM installed. Both fail.
On XP, NTVDM works, at least I can play Prince of Persia 1989

It's because the image is corrupt as far as NT is concerned. NT checks the file header more closely than 9x and the last file section extends past the end of the file. If you use a pe editor and change the size of the .rsrc section from 0x1567 to 0xdf8 then it works. The attached image is fixed.

Actually EA released this in this form. On their website, I just found another executable which they say is the IS executable for Win2k/XP. Now no wonder why.

Hmm I downloaded PE Tools and changed the .rsrc section and now it works properly and as I thought it was the PE issues only. Thanks for your efforts. How do you manage to find the section which is corrupted and what to change it with?

If you load it into windbg as a dump file it'll give the error "Image region 10a00:1567 does not fit in mapping". This isn't immediately obvious what it means but 0x10a00 is the load address for the last section and 0x1567 the size in the header. 0x10a00 + 0x1567 = 0x11f67 while the actual file size is 0x11800. 0x11800 - 0x10a00 = 0xdf8.

I am sorry but the subtraction: 0x11800 - 0x10a00 = 0xE00. Am I wrong here?

Right, I guess I was looking at the wrong number when I did the subtraction at first. Thankfully in this case the last 8 bytes of the file are 0 so it doesn't matter.

Yes you are right. It was same.
