QUESTION: Error 339: Component 'comctl32.ocx' not correctly registered: file is missing or invalid ANSWER: Comctl32.ocx is installed by the PR-Tracker setup program. This error is probably occuring because there was an error during setup. Reboot your computer and make sure no other programs are running. Then install PR-Tracker again. Make a note of any error messages. If the install succeeds without error PR-Tracker should work. If reinstalling PR-Tracker doesn't work, try installing the component manually. To do this copy comctl32.oc_ from the PR-Tracker setup files to the Windows System directory. Then use regdrop.exe (also comes with PR-Tracker) to register the component. This answer also applies to comdlg32.ocx, flp32x20.ocx, hhctrl.ocx, richtx32.ocx, tabctl32.ocx. SPONSOR 10 Benefits of Bug Tracking Software
