Here are some of the most common license activation questions:

Problem:
When trying to activate the license, the program displays "There has been a licensing problem. ESellerateErr -2009."

Solution:
Please download Flip Player. Once you install Flip Player into your Applications, Launch Flip Player > Preferences > License > Click the lock "bottom left" > Enter Serial Number".

Once you activate, open your Flip4Mac 3.3.x.dmg and run the installer. You will NOT be asked to enter a serial number since you have already activated. Once the installer has successfully completed, you should have access to viewing windows media files.

Problem:
When trying to activate the Flip4Mac license, the "Activate" button remains grayed out.

Solution:
To fix this activation issue you MUST install Flip4Mac v3 to activate. If Flip4Mac software version 2 is still installed the v3 serial number will not activate.

If you do not have this version installed, please follow the instructions below:

  • Please download Flip4Mac v3
  • Open the installer, double-click Flip4Mac.pkg
  • Click “Continue” through the menus
  • Click “Agree” to the terms of the software license agreement.
  • Select “Enter Serial Number”
  • Copy and paste the serial number provided above, click “Activate”.
  • Enter your password as requested (you may be asked more than once)

If the activate button continues to be grayed out, please contact support

Problem:
When trying to activate the license, the program displays "There has been a licensing problem. Engine could not be not installed (-2003)."

Solution:
To fix the Engine error, please delete the following files and run the engine updater:

  • Go to Macintosh HD > Library > Frameworks and delete:
    ◊ TSLicense.framework
    ◊ EWSMac.framework (if available)
    ◊ EWSMac-GC.framework (if available)
  • Also look under: ~User > Library > Frameworks folder and delete:
    ◊ EWSMac.framework
    ◊ EWSMac-GC.framework
  • Please visit http://www.esellerate.net/update and download the Engine Updater for
    Mac OS X. Then, run the updater and try the activation again after that.

Problem:
When trying to activate the license, the program displays "The maximum number of activations has been reached" appears. How do I fix this?

Explanation:
Our software End User Licensing Agreement (EULA) states that you may only have your license activated on one (1) computer at a time.

Solution:
To activate your single license on a second computer you must first deactivate the license on the original machine and install and activate the license on your second system.

You can reset your license by:

  • Deactivating the license on the original machine and install and activate the license on your second system.
  • Use our new "License Reset Tool" where you have 24/7 access to reset your own license key.

Here is some helpful information on how to deactivate and activate your license.
