Add/Remove Programs

The “add/remove Programs” feature no longer works on this PC. I have “Windows2000 Professional” installed. Everything worked fine for some time but now when attempting to use this feature the error message is:

“Object doesn’t supportthis property or method rez://appwiz.cpl/default.hta
Line 75”.

I have not been able to find the cause of this trouble or to fix it. Help will be appreciated.

This is a Gateway Performance PC with a Pentium 111, 550 processor.

Thank you,
