Win95 upgrade

I´m trying to upgrade from Win 3.11 to Win95, but when Win95´s setup program finishes its system routine check, it gives the following error message:
SU 0168: "cannot install windows because there is already an operating-system om this computer..Please get the Windows95 Upgrade."

Do I really have to erase my harddisk to install Win95?

Will Win95 transfer my Win 3.11-programs to Win 95?

If/when Win 95 is installed, how do I erease Win 3.11 from the disk, whitout doing any damage?

Thank you in advance!!

As the error message says, you'd need an upgrade version of Win 95. The best thing to do would be to get PKZIP and ZIP your entire Windows directory.
--> pkzip c:\win.zip c:\windows\*.* -r -ex -p
That creates a backup of your windows directory.
Then you can delete c:\windows and all subdirectories.
Try installing Windows 95 again. Make sure you don't install win 95 into C:\windows but rather in c:\win95 or c:\win, or whatever you'd like.
When win 95 is installed, you'll have a dual boot system.
Boot from DOS (by pressing F8 at start up) create the C:\windows directory, and type:
pkunzip c:\win.zip c:\windows -d
That'll restore your old windows. You'll then have 2 OS's, and you'll keep your old settings and application under Windows 3.x

More info if needed.

Thats sounds easy and thanks for a quick reply, but do I have to run 2 OS?
Can´t I transfer my applications (ex. Lotus Smartsuite, Homebanking and some games)
to Win 95, and run them from there.
I would prefere only one OS (Win95).

Kind regards

You can have only one OS. There are just 2 problems:
1) Windows 95 is not very stable, and many people getting rid of DOS to install Win 95 found out theyr were stuck with no OS at some point. If Win 95 crashes (it will, at some point), you could have DOS as a backup OS.
2) Getting rid of Windows 3.1 means that you'll have to reinstall your aplications, for they have to be installed from the Windows version they are intented to run from. Evn keeping 2 OSes, you won't be able to run your old apps from Windows 95 until your reinstll them. Note that, aprt from configuration, no data will be lost.
