MediaLab Run-Time error '339'

I have MediaLab and DirectRT installed on my PC desktop. Both of them were working fine, however, few months ago, when I tried to run Media Lab I got the following Windows message:

--
Run-Time error '339':

Component 'comdlg32.ocx' or one of its dependencies not correctly registered: a file is missing or invalid

(see attached image)
--

Since then, while DirectRT has continued to work properly, I was not able to run any MediaLab file or experiment. Now I need to run an experiment, but I don't know hot to get MediaLab back to work.

Does someone know what should I do?

Thanks. Best Regards,


Paolo

Best guess would be to reinstall MediaLab. You shouldn't need a new license code or anything. I expect a file or two have gone missing perhaps with the install or uninstall of another program? In any a re-install should help. Or perhaps just choosing the "repair" or "fix" option in the add/remove programs area of the windows control panel.

The "repair" option in the add/remove programs area of the windows control panel did work!
Thank you very much!
