I cannot get the Firefox setup wizard to run on my laptop, which runs Windows XP.


I have a Compaq Presario which runs Windows XP. I have 1.12 GB of RAM, a 1.59 GHz processor, and more than 30 GB of space on my hard drive. I can download Firefox, but I can't get the setup wizard to run. After I get it downloaded and try to run the wizard, my computer hangs up. I have tried both saving it and running it right off the bat. Neither way works. I need to have Firefox on my machine, so any way I could get help with this problem would be great. Thanks.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with installing Firefox.

You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes installing work.
