Windows 95 CD-ROM Contains Two Setup.exe Files

There are two Setup.exe files on the Windows 95 CD-ROM. One is located in the root folder of the CD-ROM and is 3664 bytes in size, while the other is in the Win95 folder and is 5184 bytes in size.

Note that the version of the Setup.exe file in the root folder of the CD-ROM is not a beta copy or a damaged version of the Setup.exe file.

You can use the Setup.exe file located in the root folder of the CD-ROM to start Setup without manually changing to the Win95 folder first. This version of Setup.exe calls a file in the Win95 folder called Suhelper.bin, which unloads the original Setup.exe and then loads the version of Setup.exe in the Win95 folder. Suhelper.bin also passes any command-line parameters to the version of Setup.exe in the Win95 folder. Setup then continues normally.

Suhelper.bin is necessary because there can be only one instance of Setup.exe loaded in memory at a time.
