Hi, I purchased PDF 2012 in November of last year. I have tried many times to install it on my computer ( Windows 7 64 bit ) with no success. It will install but it
completely takes over my computer turning all my icons into pdf icons & I cannot access any of my progams. I have gone through all sujestion in the Q & A pages & still had no success. I tried disabling AVG still no success. If there is no solution to this problem I would like a full refund.
