I upgraded to a new computer and I had to download PAF again. I downloaded it fine the first time, then I decided a couple of days later to add the Companion. The companion took the place of the paf, but it was not what I expected, so I deleted the companion. I have tried to download the PAF 5 again and it downloads but I cannot open it. After asking if I want it in English and it loads, a message saying" Install shield engine(ikernel.exc) could not be installed. System can not read the specific device"Help!! Should have let well enough alone.!!
