Add/Remove Programs will not open

[Mike]

When clicking Add/Remove programs in the control panel, the hourglass flashes for a second but nothing happens. Running appwiz.cpl from the run box does the same thing. I ran Dial-A-Fix to re-register the Control Panel items but it gets an error on appwiz.cpl. Running "regsvr32 appwiz.cpl" gives the error "Loadlibrary (appwiz.cpl) failed - a dynamic link library (DLL) initialization routine failed". Using Procmon I was able to track down the missing dll file. Oleaccrc.dll. I downloaded a copy of this file into the System32 directory, then ran "regsvr32 appwiz.cpl" and the Add/Remove Programs works again.
