I got an error code 1722 when I tried to install FSX. It says it has something to do with the registry.Does anybody know of a free registry cleaner?Regards,jack

Thanks Jim for your help. My DVD/RW internal drive just went out on me. I'm getting a strange message when I boot up my system.It is saying: " The software you are installing with this hardware:JMicron JMB36X Controllerhas not passed windows logo testing to verify it's compatibility with Windows XP. Continuing you installation of this software may impair or destabilize the correct operation of your system either immediately or in the future. Microsoft strongly recommends that you stop this installation now and contact the hdwre vendor for software that has passed Windows logo testing."-Continue Anyway or -STOP INSTALLATIONI chose to 'Stop Installation' and it does nothing. It keeps giving me the same screen information as above over & over again & clicking the STOP INSTALLATION does nothing.....Anybody know what's going on here? If I move the message down to the bottom of the screen, I can use my computer and access my email or google etc., however, I still can get my CD/RW burner to work. I will light up and spin, but does not even recognize my FSX install disk and when I try to access FS2004, it says: 'Insert disk 4 etc.' and nothing happens.Any ideas?Regards,jack

Jack,Whenever you install hardware that does not meet Microsoft's compatibility standards, you'll get this error. You can select "Continue Anyway" and most of the time it will work but with limited capabilities or you may run into future problems (I personally have never had a problem in XP by selecting "Continue Anyway"). The best way to install "old" hardware is to get the latest WHQL certified driver for the device you're installing. I Googled JMicron JMB36X Controller and Google offered me several links to the latest and greatest software/drivers for your hardware. Here's one - http://drivers.softpedia.com/get/Other-DRI...512600104.shtmlI believe FS2004 requires CD4 in the CD/DVD Drive in order for FS2004 to start up. It's to prove you are the owner of the software and it's not pirated. So you'll need to get the CD/DVD drive to work and hopefully installing the latest drivers as stated above will fix things for you.Best regards,Jim

Thanks very much for the valuable information. I'll pursue this problem based on your helpful inputs.Regards,jack
