HELP ME PLEASE!!!!!!
i have just installed Messenger Plus in my pc. now, i saved it on my desktop, then i wanted to bring these new files ( "Detoured.ddl", "MsgPlusH.ddl", "MsgPlusLoader.ddl", ecc.) in an other folder and i did it. but when i tried to remove the icons from the desktop i couldn't do it. when i try to open these files, a window appears saying:

Messenger Plus! - Installation Altered
Messenger Plus! has not been installed properly on this system.
Please download and install the setup package of this program.

When i try to dolete these file san other window appears saying(translated from Italian):

Error during the elimination of the file or of the folder
Impossible to remove (NAME OF THE FILE): access denied.
Please control that the disc isn’t full or protected by writing and that the file isn’t actually in use.

What should i do????????

I think that you should install Messenger Plus! again but in a proper folder (the standard one is better), and don't move the files! Else it won't work properly anymore. Once you have re-installed Plus!, it's probably possible to delete the files on the desktop.

You should try to remove Plus! under Add/Remove Programs first though, and then install it again.
