Can't open Folder Options in WinXP Control Panel

In Windows XP Pro, if I double click on the Folder Options ikon in the Control Panel I get an "Open With" window asking me to choose the program I want to use to open the file--in other words, I don't get the Folder Options window. The other applications in the Control Panel seem to work OK. I am able to access Folder Options in the Tools menu in Windows explorer.

I have tried running regsver32/i shell32, but this had no effect on the problem.

Can anyone suggest how to fix this problem?

If its opening properly in tools menu, it should also open in the control panel. Seems like a virus problem. I'd suggest to scan your PC once and check if its affected. Relpy me so.

I have done a thorough virus scan, with no virus detected.
