McAfee And Windows 7 64bit Crash?

I have had an ongoing subscription with McAfee for several years and recently bought a new laptop loaded with Windows 7 64-bit. This came with a free 60 day trial version of McAfee antivirus software installed on it which seemed to work fine. When the free trial expired I decided to use my current subscription, (which allowed protection for up to 3 different machines and had used on my old laptop) on my new laptop. When I called McAfee to do this I asked the rep if it was compatible with Windows 7 and I was told that it was. After receiving download instuctions via email I noticed that Windows 7 was not on the list of compatible Operating Systems, just Win 2000,Win XP and Win Vista. I called McAfee back to verify Windows 7 compatibility and again, they assured me that is was fine. So I went ahead with the download. I clicked the RUN button for DMSetup.exe and then RUN for the IE Security warning as per the instuctions from McAfee and the BLUE SCREEN OF DEATH appeared for about 2 seconds and my machine shut down! After attemting to restart it went into Windows Error Recovery mode then Launch Start-up Repair and then could not repair problem and shut down again. This sequence repeated every time I tried to restart. I called McAfee back and again I was assued that it was compatible with Windows 7 and they said I should do an online diagnostic on their site. I told them this was impossible as my machine would not start up even in safe mode so I could not even go online at all! They finally said to contact the maker of my machine as that is where they thought the problem was, which I did. The maker told me that the machine would have to be reformatted after several attempts to get it going. 1 Day and $200.00 later with a reformatted machine I called McAfee again and told them of the crash and that I thought their software was the cause. They advised me this was impossible as their Software is compatible with Windows 7 and that there was no problem in trying to install again. Hesitantly I tried the download again. At the same point in the download the exact same thing happens...shut down. This time thankfully, the system recovered after several attempts. I called McAfee AGAIN and told them they had nearly crashed my machine again! They said my operating system must be corrupt. I told them it was reinstalled only 1 hour earlier so how could it be corrupted? I insisted on talking to a technical rep which they agreed to (and didn't charge me the $9.95 per incedent fee thank you very much). I finally got an explaination after 6 hours, 5 phone calls. McAfee does not have a product that is compatible with Windows 7 64-bit yet. It should be ready in a month or so. They then offered to extend my trial version for an extra 30 days! I said "you just told me there is nothing compatible with Windows 7 64-bit" so what good is it to extend my trial version. Besides I was told to uninstall the trial version before installing the new one so it was gone from my machine.
