The ultimate Yahoo Messenger Polygamy patch to run multiple instances of Yahoo Messenger! Perfect for those who use several Yahoo ID's. With this you can login to as many Yahoo ID's that you have. Please read all included documentation before installing and/or using. This will work with 8.x versions of YM. Also includes built in ad killer for chat and webcam features, also comes with the Ravebuttons.ocx file.

Installation Instructions:

Before installing, please read ALL included documentation! Run the installation setup program to install Y!Multi Messenger. This will automatically install to C:Program FilesYahoo!Messenger. If you have installed Yahoo Messenger to a different folder, make sure to reflect the correct path in the Y!Multi Messenger setup wizard. Failure to have it install to the Yahoo Messenger program files folder will likely result in dll (driver file) errors.

Up/Downgrading Instructions:

Should you upgrade or downgrade versions of Yahoo Messenger, please delete the Y!Multi Messenger.exe file from the Yahoo program files folder first, then uninstall/upgrade Yahoo Messenger. Then if you are wanting to install Multi, make sure you have the same version of it and install it. It is important to delete the Y!Multi Messenger.exe file before up/down grading it as sometimes it may not get overwritten and can cause errors!

How it works:

Y!Multi Messenger is technically a "fixed" form of Yahoo Messenger. It is the Yahoo Messenger (ypager.exe or yahoomessenger.exe) file modified to allow multiple instances open. That is why it is imperative that Y!Multi Messenger be installed to your Yahoo Messenger program files. That is also why it depends on the needed Yahoo Messenger files to operate properly. Y!Multi Messenger works just like Yahoo Messenger, there is nothing else you need to do to have it work for you. Simply use Yahoo Messenger like you normally would, the only difference is that you can have several of them open at once.

Uninstalling Instructions/Notes:

Should you choose to uninstall Y!Multi Messenger, just simply delete it from the Yahoo Messenger program files folder. Y!Multi Messenger does not have an uninstall feature due to it being a modified ypager.exe file. If Y!Multi Messenger had the uninstall feature enabled, it will actually uninstall ALL of Yahoo Messenger. Should you uninstall Yahoo Messenger, it will actually show up as uninstalling Y!Multi Messenger. However, it will all do the same action of uninstalling Yahoo Messenger altogether.

Extra Notes:

Y!Multi Messenger is in no way endorsed nor supported by Yahoo! Inc.
Should you run into *.dll errors when trying to launch Y!Multi Messenger, please uninstall (directions above) it AND uninstall/reinstall Yahoo Messenger as well. Please note that you must run the same version/build of Yahoo Messenger and Y!Multi Messenger.
