#1 Upgrading Windows 9x/Me when you get an Error Message SU0168.
Caution: It's possible some OEM upgrade versions may be specific to them. Using a different OEM version to upgrade a non-matching OEM Windows could possibly damage the existing Windows. That would force you to reinstall the current Windows with possible loss of data. It's a possibility, so please be aware of it! However, this method has never failed to work for THPC.
How to Upgrade Win9x using true MS-DOS if Error Message SU0168 occurs:
1. Note the name of the current Windows folder (usually C:\Windows).
. Backup important data, passwords, settings, etc.
. Boot with your Win9x boot disk and see if you can read files on a CD. If CD is not supported,
copy the contents of the OEM CD to a new folder on hard disk (like D:\Win98).
2. Boot with Win9x boot disk inserted (leave it inserted until first reboot during OEM install).
. At the A:\> prompt, type and press [Enter] after each line - be careful with spaces!
REN C:\WINDOWS\WIN.COM WIN.ADA
REN C:\WINDOWS\WINVER.EXE WINVER.ADA
where your current Win9x is installed in C:\Windows (alter if necessary).
3. Insert the new OEM CD, and type: (but use Z:\WIN9X\SETUP /IS for a WinMe OEM CD)
where Z: is the CD letter, or Z:\WIN98 is the location of CD files on hard disk.
(note: there's a space between SETUP and /IS)
4. If OEM wants to install on C:\Windows.000, you change it to current Windows folder.
. If the install fails to start, exit setup, and rename the two files back. You can now reboot
back to the original Windows without loss.
NOTE: Do not be tempted to rename the Desktop folder or Desktop.ini, or do anything else when upgrading - you would risk the loss of many current Win9x items!
