Firefox doesn't know how to open this address, because the protocol (tomtomhome) isn't associated with any program.


I restored my AcerPower FE Desktop to the way it was when it was new on 7/24/10, because of scareware. Before the restoration, I never had a problem updating the maps on my Tomtom GPS unit. Since the restoration, when I download TomTom it does not download to my desktop but it downloads to a download folder. I have sent it to my desktop and then double click to install, but nothing happens. I get the message that Firefox doesn't know how to open this address because the protocol (tomtomhome) isn't associated with any program. Can anyone help me please? I need easy to follow instructions as I am not tech savy. I have Windows XP and Firefox and 90 days of free Norton. Thanks so much.

Additional System Details

This happened

Just once or twice

This started when...

After the desktop restoration took place.

Need to get this corrected please.

Helpful Reply

Can anybody help with this? I am thinking because maybe because my TomTom is a few years old, that they will no longer allow me to download it for free map updates.

Hi, I'm also having this trouble now and in search for a solution like you guys. Found this site talking about Protocol Tomtomhome and it explains other difficult terminologies as well. Though I haven't tried it yet, I think it has a tool that can help troubleshoot our Tomtomhome problem. I'm still reading though, and trying to understand cause terms were a bit techie to understand.
