Universal Jnrzloader works for all windows messenger, MSN Messenger and WLM versions. Simply start your messenger with this program instead of the regular icon.
Use with different versions:
If you have installed messenger in a different folder, place a shortcut to this on your desktop and add " -<path to messenger.exe>"(without quotationmarks) to target field (rightclick icon > properties - example:
"I:\Programma Downloads\ProgrDownloads 2\Chat\msn\jnrzloader\universaljnrz\MSNLoader.exe" -C:\Program Files\MSN Messenger 7.5\msnmsgr.exe). Once you've done that you can simply start your regular Messenger with the desktop icon and the second (other version) with the jnrz loader icon (you can alter the icon too if you wish to do so).
