Welcome to Adobe Forums.
On which windows you are working ?
Which version of Adobe Presenter you are using ?
You can use Start -> Control Panel -> Program and Features (Windows 7 & Windows Vista) to uninstall Adobe Presenter.
Note : For Windows XP , Start -> Control Panel -> Add or Remove Programs
Thanks for reply Vikram.
I am using Windows 8.1 Adobe Presenter 9 (latest)
What you suggest is for uninstalling but what I want to do first is to deactivate, so that I can reinstall it.
There is no option to deactivate.
Please go ahead and uninstall it and it will deactivate
The serials are linked to your sign in. So when you have signed out basically the serial is deactivated
Please click on sign out first and then uninstall
Doing so will deactivate Presenter and you can sign in again and give the same serial key to activate presenter
Hope this resolves your issue
