CookieRevised's reply to messenger plus msg appears evry time i restart" and follow the instructions.
If that doesn't help then describe your problem as accurate as possible:
- What is the _exact_ and _complete_ error message you're getting (make a screenshot if possible)
- What is the _exact_ and _complete_ version number of Messenger Plus! you've tried to install?
(you can find this by right clicking the setup file > select Properties > select the Version tab > select File Version in the list)
- What is the _exact_ and _complete_ version number of Messenger you are using?
(you can find this by going in Messenger to the menu Help > About Messenger)
- What is the version of Windows you're running?
- When exactly does the error occur?
