Loading yahoo messenger and am getting cannot load resource DLL. what does this mean?

ANY Yahoo! Messenger program will not install properly if a former program, or an incomplete install, has not been completely deleted from the computer first. Delete all Yahoo Messenger references from the registry. Use the Control Panel > Add/Remove method, then double-check by going to Start > Search > files and folders > Yahoo! Messenger (notice the exclamation mark in the title). Write down and delete all references manually, except for your Profile folder. Also, go to My Computer > Local Disk > Program Files and delete any Messenger files there. You might consider downloading CCleaner to help clean out the registry safely, but be sure to back up the registry first with the program. (It's also a handy program for deleting temp files, history, etc in one click - for a faster, cleaner computer) Download and SAVE the program directly from the File Hippo web site. Install it only AFTER completely cleaning the registry of remnants. Download the most recent version of any Yahoo Instant Messenger (highest number, top of its list) Some firewalls have issues with installing Messenger, but disabling your firewall while online is VERY dangerous! Usually, by installing after downloading, the firewall will ask for permission to run the program. If you use Internet Explorer 8 as your browser, Yahoo Messenger 10 will not work properly without Flash and Java programs also installed, and possibly the .NET framework update.
