Bests & Worsts Reviews from Amazon

Except for one critical problem, this is an excellent alternative to Adobe Acrobat and seems to integrate well with that program when sharing comments and editing etc etc. I would recommend it highly except for a fundamental problem with the way this software is activated and the likelihood that it will stop working due to this feature. PDF Converter Professional 7 seems to identify the process of adding/removing external drives as significantly changing the computer and flags this as the user installing the software on a new computer. It then asks for activation, which would not be a big deal except that there are a very limited number of activations available to the user before the software stops working. I phoned the help line and was told to reinstall the program with antivirus and firewall turned off, which was done, but the problem continued. I phoned again and was told to not only do a clean install but to register the software online. Registration is separate to activation and requires personal information that I am not particularly happy giving to a commercial company, but in this case I did. The software continued to ask for activation after external drives were used. External drives are commonly needed to back up data files and transfer large video files, so it appears that this software will fairly quickly become unusable for many people who need to use external drives. I use other much more expensive software that requires activation, but does not have this problem. I am returning this software for a refund.
