I uninstalled Hitfilm because it wasn't reading the .mov files and I thought reinstalling it would fix this error (I don't know why). The uninstallation process was taking more than 15-20 minutes and it seemed to have been stuck at some point, so I canceled it and restarted my pc. After downloading the installer again I tried running it and it displayed this message - ''A previous installation for this product is in progress. You must undo the changes made by that installation to continue. Do you want to undo the changes?'' Even after hitting 'YES' the same message pops up again the installation doesn't proceed.
Please help. Thanks for your help in advance.
