Why doesnt yahoo messenger for vista install on my new hp laptop running on windows vista home premium?

i have a brand new hp laptop that runs on windows vista home premium and no matter how many times ive tried i absolutely cannot install yahoo messenger - not even the vista version. the ymsgr_vista_us_setup.exe file downloads onto my desktop, i double click it, installation begins, im able to get to the window that says 'installing - please wait while yahoo! messenger for vista is being installed' and it looks like the download is going on just fine until halfway through when installation stops and i get the message 'install unsuccessful - yahoo! messenger for vista did not correctly install. this may have been due to other open applications or incomplete installs. please try the install again after restarting your computer.' i use a gprs connection, so the only application thats running at the time of installation is 'one touch access' which allows me to access the web using my n series nokia phone. i fiddled with norton antivirus' firewall settings in an effort to figure out whether that might be causing the problem, but i get the same error even after turning off the firewall. i really love yahoo messenger and i dont want to stop using it. i dont want to go back to xp for the prime reason that i cant even think of subjecting a spanking new laptop to an os change already. please help!Why doesnt yahoo messenger for vista install on my new hp laptop running on windows vista home premium?
According to Yahoo, this product is still in development. On the home page Yahoo says, ';Preview the new Yahoo! Messenger for Vista. Help us develop our latest instant messenger designed exclusively for Vista.';



It also says, ';Note: While testing this product, you can still use your current version of Yahoo! Messenger (8.1 or 9.0).';

I'd suggest you completely uninstall EVERYTHING (all files and folders) related to Yahoo Messenger. You might have to use Vista's more powerful search function rather than the default search box (lower left corner of start menu.) In any folder window select Search Tools %26gt; Search Pane. You'll have a list of options (all, email, document, etc.) Select all. In Location: select hard drive. Leave Date: and Size: set to any. Check the box to include non-indexed, hidden, and system files. Run the search. Delete any references to Yahoo Messenger. The reason for deleting all files and folders is they can sometimes interfere with a clean reinstall.



You can now install either 8.1 or 9.0 messenger. I'd recommend 8.1 because the 9.0 version is also a Beta (in development and testing.)

If Vista won't run the older version, it's probably one of Vista's many compatibility issues. But Vista does have a Compatibility Mode that sometimes lets you run older programs. (Yet another Vista compatibility issue with its own Compatibility Mode feature.) This tech article give more information:
