Well after digging out an old 'Windows 3.11' .zip on my MacBook (I knew I saved it there for some reason!) I was able to install Windows 3.11. The install took about 10 minutes or so. Mouse support worked fine during the installation, but it seems to have stopped working once I got to the desktop. I'm sad to think that there will be no updates to this App since it was pulled, but I'm happy I got it. Maybe they'll allow it to be re-submitted after some tweaks, but it's doubtful.
The iPhone version is fun, but it feels cramped. The iPad version is great, plenty of room for screen & keyboard. Maybe we'll see a return of this App in the future, but for now I'm glad I bought my copy so I can fool around and have some old-school fun. 😀
For the install I made a folder inside a folder. 'Win31' and inside that 'WinInst'. WinInst was the root folder with all of the Windows installer files inside of it. I renamed the 'Win31' folder to .app so it was 'Win31.app' which allowed iTunes to upload it to the iPad. Then in DOS I used the REN (rename) command to remove the .app (I think it was: REN C:\WIN31.APP WIN31).
Then I dug down into the directory and started the Installer setup C:\WIN31\WININST\SETUP.EXE. The install took about 10 minutes as I said before. You can NOT just use an .ISO file. You must move it to a folder or maybe a .Zip file. DOSBox can unzip files, but I don't think it has any support for .ISO files. Also it should be noted that doing a simple 'unzip archive.zip' command will unzip the file into the main directory, easily making a mess of things. So keep your folders/files organized. 🙂
