Does anyone know about "fatal error 2502 and 2503"?

This error shows up when i want to remove or install a program.
also following this error i get a message "ensure you have appropriate privileges to this machine ".
i have windows xp home edition and yes it has been activated through microsoft.

anyones help would be greatly appreciated.

thanks.

The program below called an unsupported MS-DOS function:
Error 2503
The workstation failed to boot.

Error 2504
The file below is corrupt.
Error 2505
No loader is specified in the boot-block definition file.

...
since it appears as if this whole URL is not showing up, Here is how I found it:
www.support.microsoft.com
In left window for "solutions containing...(optional)" I typed in:

strgzr - easiest way to put a URL in here is to put tags around it so that all but the title you give is hidden and the title displays as a clickable link. I will use http://www.sysinternals.com as an example below.

Done as follows (don't use the spaces when you do it - I had to put them in so everything would display)

[ u r l = and put the url here ] Title you want it to have [ / u r l ]

The result would look like Sysinternals Web Site .
