"Invalid serial number or activation key" Error.
I am trying to install TTWin3 but I keep getting an error message stating 'Invalid serial number or activation key', what is wrong?
If you have received the serial number and activation key via e-mail, just copy and paste the serial number and activation key rather than entering it in manually. If entering the serial number and activation key manually, please note that the activation key comprises five groups of four lower case letters separated by space characters.
Another possible cause is the activation key that you are entering is not licensed for the version of TTWin3 you are trying to install. For example 22.214.171.124 to 126.96.36.199 can use the same serial number and activation key. A serial number for 3.2.1.x will not work with the next upgrade version of TTWin3, such as version 3.3.0. A similar situation occurs for versions greater than 3.8.0 which use certificate files with a .tcf extension rather than serial number and activation keys.
If the serial number and activation key still refuse to allow installation to commence, please contact Turbosoft support.
