Yep, with FW's particularly it's hardly vital to keep it up to date if it's already working fine on your box. If you find a version you love... keep that installer! That goes for a lot of different apps. Shadow Defender 184.108.40.2065 for one. There's a version of ImgBurn (220.127.116.11)... I swear all the ones since won't burn bootable discs correctly. At least not for me. So I stick with that one to slipstream updates into XP. Macrium Reflect Standard 5 didn't work like 4.2 does for me... I'll just come out and say it. It was crap. It almost hosed my machine. I wouldn't recommend the Standard version of 5, though the Free seems to work ok. AV's on the other hand, I would want the up to date engines (real-time ones anyway). They are interacting directly with malware, and I mean REALLY directly. If I came to find a new version didn't work right on my machine, I wouldn't stick with an older one... I'd pick a new product that did work. Unlike FW's & imaging apps, the pickins on quality products aren't slim. There are plenty of competitive, quality options out there.
