do you need to update adobe air?
Hamzi, if you are still having problems please check your system meets the System requirements for VideoScribe desktop. I would also make sure you are downloading the software from https://www.videoscribe.co/Download rather than another source. If you computer meets the specs and you are downloading the genuine software please log a ticket via https://help.videoscribe.co/support/tickets and include details of your operating system and we'll do our best to get this working for you.
