I have an SS board and I was using 2.63 but per the www.warp9td.com I need to use 3.041. I uninstalled 2.63 then tried to install 3.041 and I get an error message that says installation failed. I tried several more times with the same result. Any troubleshooting ideas? Thanks.

Sounds like you may not have gotten a complete download. I'd try to download again and then try to install.

I downloaded 3.042 and it fails to install also. It hangs and when I check the application event log it says it failed in irsetup.exe. This is running on a Dell Inspiron 1525 with 2 GB of memory and Vista Home Premium. I had no problems with 2.63. Anyone have any suggestions?

Make sure that you uninstall the previous version and the driver. There is a newer installer in the new version so it's best to start with a completely clean install.

I did an uninstall and even removed my virus protection in case it was getting in the way. Still no luck. I start installation and nothing happens for quite a while but then eventually a window pops up and says installation has stopped due to an unknown problem. I am still stuck :-(

Hello,
I would try the newest version of Mach3 (3.042.0xx) and this may fix your trouble. This version has an all new installer, I had seen this problem 5-6 times and knew I needed to do something . So please use that install and tell me if you have any luck with it.
Thanks

Nope, no joy with 3.042.014 either. Still dies during install.

Well.. that is the first time I have heard of that one..  I havea Vista machine here and I can install fine.. Please log on as admin and try to install.. That should help..
Thanks

There is only one account on my system and which of course is the administrator. I checked just to be sure and also tried to install yet again. It still hangs. I think I am going to download a registry tool to see if I have a corruption issue. Maybe one of the previous uninstalls didn't complete properly.

Hello,
Please try installing and unchecking the install Parallel port driver.. that should help.
Thanks
Brian
