I asked for a refund multiple times after the file I got kept giving me an error and I was never able to open. The file was 18 gig!!! And then it was trying to take over 20 in addition to install. I'm not sure exactly how much space it would have taken after installed because my machine which had 50 gigs available before I downloaded and tried to install, kept giving me an error that my hard drive was full and there was no more space to install. I finally deleted the file because my machine was running so bad after using up so much of my HD. Customer service was prompt but extremely unhelpful. It was just a time-wasting run around at them trying to seem helpful, but not at all. I let them know I was not interested in using up all my space for the manual and I wanted a refund because I was never able to install and open the manual. I got nowhere with them and I finally gave up. My time isn't worth the $12 I spent. Check their BBB rating, it is an F. Wich I had saw that before. Oh well, stay away!
