Reinstalling Win95 refuses Certification number

I am forced to reinstall Windows95 due to GPF in the modem support.
I will first try to reinstall with the old Win95 still on the hard disk to hope that I get all my installed applications back automaticly.
When I start setup it asks me for my certification number (it's a OEM number).  I have the original certificate but setup keeps telling me the number is not valid.
What should I do to convince setup the number is valid ?

Can you still boot into the system?  If you can get the number from  settings-->control panel-> system  -> general.

I should have explained. It may be for some reason the number you are using is different to the OEM number it thinks you need.
Try using other OEM number, or another CD

try this:20795-OEM-0002723-75302

No, you have to use the orignal OEM number if you are performing a re-install. Try this tip I got from another page at EE.

1) Make a new directory on your hard drive. (i.e.  C:\Win95)

2) Copy the \Win95 directory from your Win95 CD to the new directory on the hard drive.

3) Use extract.exe to extract the file SETUPPP.INF from PRECOPY2.CAB

4) Open LAYOUT.INF in a text editor. (Notepad will do this)
      Search for the string "SETUPPP.INF".
      You should find: setuppp.inf=2,,4550

Change the 2 to a 0 to read:


              Save the changes.

5) Open SETUPPP.INF in a text editor. Search for "ProductType".

              Change it to read:  ProductType=1

              Save the changes.

 6) Now run setup to re-install without a CD Key number.

Sounds good arunm!  (Now, where have I seen that before?)  :))

Are you running setup from a Dos prompt?
If so, try it from Windows Control Panel - Add/Remove Programs instead.
If you can't start Windows normally to run setup that way, try it from safe mode.
Let me know what happens.

My system was indeed originally setup with another certification number than the one on my license paper.
Thanks to arunm I can try to reinstall with the original number... but the points go to ORC.

Thanks guys.
Did the answer from ORC solve the problem?
Was the re-install successful with the INF tricks?
