Sharpeware

The most usual cause of this problem is that the component listed was previously installed by a different application - but not into the correct windows\system32 directory. If this is the case Windows cannot then register an update to that component in its correct location.

To correct this try to manually register the component (e.g. Threed32.ocx) as follows, using your Windows System folder as the path (example for XP):

Click 'Start, Run'.
Type in: Regsvr32.exe C:\Windows\System32\Threed32.ocx
Click 'OK' to run the registration program.

The program should return that the component was successfully registered. If the registration program again returns that the component cannot be registered, then first unregister it as follows (with the /u switch):

Click 'Start, Run'.
Type in: Regsvr32.exe /u C:\Windows\System32\Threed32.ocx
Click 'OK' to run the registration program.

The program should return that the component was successfully unregistered. Repeat the first step above to now register the component. The program should return that the component was successfully registered.
