I was very unhappy with the installation. Firstly, I had previously purchased a copy in the past and was unable to complete the installation to a full copy. Order ID: PDF-PRO140120-6228-84151 Recently, I bought another copy of PDF Pro 10. Order ID: PDF-PRO141113-1341-47199 Neither of then have worked successfully. The recent download worked OK. I received the Key to convert to the full version - It never work and I am still using the download version, having now purchased the software twice. I contacted Tech support - initially no response. After second attempt they sent an email that referenced to the correct download site and sent me the Key again. The download was successful, but the conversion did not work. So I am still using the download version and I am not a happy user. I have a strong IT background and have not installed & uninstalled PDF Pro 1- several times without success. Whilst I do like the software, it infuriants me that every time I use it, I am prompted to re-enter the Registration Key. I must use the software 10 times a day, so I get upset with you guys about 10 times a day. I have recommended this software several times to my friends and theirs works OK, which further infuriates me.
