I am unable to install pdf architect on 3 of the 5 computers that we have purchased licenses for. They are all the same make and build of computers. I have disabled the antivirus and firewalls and used the regular and offline installer. The 2 that worked pretty much installed immediately. The 3 that will not install just sit at a screen saying “ download and install” Sometimes it even says it is installed but I never get the finish button and I am never able to find the program in the start menu. I have attached a photo the install process. It will sit at this screen for hours. Any ideas? Thanks!
