I have KAV 2006 and wanted to make a rescue disk. So, I followed the instructions and got PEBuilder and then ran the KAV wizard. Nary a peep from PG. But I got 10 errors and 9 warnings and PEBuilder stopped because of them. I asked at KAV forum and a member of the Russian lab and a Russian support team member both answered but I didn't mention I had PG running as I had no idea at the time that there was this supposed conflict. I then tried to delete the folder that had about 2,000 files from PE builder to try again but a file "petmphive" could not be deleted as it was supposedly in use. That problem led me to search about this and I found posts stating that PG from way back in 2004 is incompatible with PEBuilder and that PG will not alert or anything but will cause most of the errors I saw when trying to build the ISO. I tried searching here for threads and was informed there are no threads that contain the word "PEBuilder". But I have this thread which I found reference to in another forum. http://www.wilderssecurity.com/archive/index.php/t-55372.html So, from 2004 to now this issue remains? DiamondCS didn't do anything or is this issue fixed in the latest version of PG? I am still using 3.15. I gather that if I disable PG before opening PEBuilder that should work?
