Installing the Windows 95 updgrade with minimal Win 3.x system files on hard drive

Posted on 1998-10-28

I know that this is possible, I just don't remember WHAT I did.

I have an upgrade CD for Windows 95.  Supposedly it requires that you have Windows 3.x on your system before it will work properly, but I know that the COMPLETE Windows 3.x does NOT have to be installed for the Windows 95 upgrade to work.

There are like only 3 or 4 files that the Windows 95 upgrade looks for when it runs.  If those files are not present it will not install.

I need to know what these files are.  I think one of them was GDI.EXE.

I believe you actually only need from Windows 3.x to make the Win95 upgrade install.

This claims to be for Win95 OSR2, but I'm certain it'll work as you need it to:

This is more for doing the reverse, using an OEM 95 to install on a machine that already has windows, but option 3 listed should be able to be used in reverse - to change the type of install from an upgrade to an "oem" version.

Try this:
From any text editor, create an empty file in the root directory of your hard drive named WIN386.SWP.
Then run Windows95 setup to do a full install.

If you want a clean install with the win95 upgrade, all you need is disk1 of a win31 install.  Just run the win95 setup, and when it asks for the previous version of windows, browse to the a drive, it'll be happy, and install a clean version of windows on your computer

Here is what to do.
Create a file in dos editor or notepad and call it "WIN.CN_" (no quotes)The file does not need any text in it. Simply the file will do.
Place this file on a floppy disk.
When Windows Upgrade setup asks for you to locate the directory where win is installed navigate to the floppy with the WIN.CN_ file is.
Windows 95 upgrade will accept the file as an installed copy of windows.
This will work I have done it lots.
Good Luck!
