Posted by Appeon Support on 09 August 2017 02:46 PM


You may encounter the "Error 20037 or 20038: Your license is not activated within the valid period, or your license activation fails for changing the system time, please confirm and then re-apply for the license" as shown below in about 30 days after you applied a new license into your AEM.



1. Download the attachment

2. Unzip the downloaded

3. Run the unzipped appeonkeymodify.exe using Run as administrator.

4. Apply a new license required from Appeon.

5. Restart IIS.

Note: If there's anything stopping you from running the AppeonKeyModify.exe, please exit all your anti-virus software and try again.

If it does not resolve the issue, please click Activate > Generate Activation Request or Upgrade License > Generate Activation Request on the AEM Licensing page to generate an activation.bin file and send it to along with the error screenshots.
