unable to install express 4
brand newbie, trying to install Hitfilm express 4. dialogue box says sorry, unable to install must leave error. I am on a Lenovo laptop with windows 10 os. Following all prompts over and over. It quits just short of where I am suppose to click on a social media to tell friends about Hitfilm. Really want to use Hitfilm looks like such fun. Anybody help me figure out where I'm going wrong. Thanks , User name vidsfixer. AKA , Al.
