I had a dinosaur computer before I bought a new one today and it has yahoo messenger. Why can't I install yahoo messenger on this new computer?

i know they have yahoo messenger for the web now with out no down load but just want to know why yahoo messeneger wont download all the way on my pc it keeps on saying file not there or its been corupted

so I can download and after I do that I want to install but it says that I don't have enough space on my disk and I must clear another 100 MB. but my disk its about 90 GB so I don't think yahoo messenger is bigger then that... I wanted to try an older...

I used to have it on my computer then I uninstalled it. Now I want it back and everytime I go to install it, the install won't even start. I hit "run", I even tried saving it to my desktop and opening it that way, and it still does not work...

I' VE DLELETED IT BY ERROR AND I CAN' T DOWNLOAD IT AGAIN. IN THE CONTROL PANEL OF MY COMPUTER EXISTS ALREADY YAHOO MESSENGERL BUT I CAN' T DELETE IT FROM IT, AND DOESN' T PERMIT IT TO ME TO INSTALL IT.

If I cant install yahoo messanger how can i still chat with my family thorugh webcam?

It installs. But won't link to facebook. Tried with security on and off. Cookies on and off. Standard install with home page, custom install without home page. Makes no difference.

I've tried pretty much everything that people said to do on the internet and it still won't install. Please help. Any tips or something would be very helpful. Thanks in advance.
