I can't download yahoo messenger...:([email protected]

You need the following OS to support Messenger
Windows 2000 / XP / 2003 / Vista / XP64 / Vista64 / Windows7
If that is not an issue read on.
Make sure your IE is up to date - even if you run another browser as default. IE is interlinked with Yahoo Messenger
You can use an update checker for this and it will also check the support software needed to run Messenger - Flashplayer (IE) Shockwaveplayer(IE) and Java

If you use another browser -check that IE is not set to 'Work Offline' under 'Tools' and has a red X through globe
The problem is probably due to a mal-function of the uninstall software.The Yahoo Messenger uninstall software is notorious for leaving files and fragments behind creating conflicts with the incoming software
Close all programs when uninstalling / downloading and uploading.
If you tried to uninstall the old Yahoo Messenger program from the Control Panel and failed to back it up with a visit to the 'C' drive, you may have old software conflicting with the incoming software trying to share the same folder.
If you have Vista the whole Messenger folder should have been removed during the uninstall.
Check
Start > Computer >> Local drive (C) >> Program Files >> Yahoo >> Messenger. - The Messenger folder should have been deleted and not seen. If the Messenger folder is still visible - delete it.

If you have a pre-Vista OS, the Messenger folder remains, and inside, only one sub-folder should be seen. This is the 'Profile' folder and contains all the message history. All other software should have been deleted.

Manually delete any other folders and files before moving on

If you have Vista you may be denied being able to delete folders - in this case you will have to disable the 'User Account Control'
Start > Control Panel (Home) > User Accounts and Family Safety > Add or remove user accounts > Continue > Go to the main User Account Page > Turn User Account Control On or Off > Continue > Uncheck control box > OK

Download 'ccleaner' and use it daily. Run it through a couple of times,using the factory settings and the 'Run Cleaner' control until 0 bytes are seen to be cleaned following a scan
Run the 'Registry' from the left hand toolbar but 'Save' any changes after opting to 'repair' errors.Never make changes to your Registry without saving the information.
