SYMPTOM:
After users go through the Server Activation dialogue and then try to use the activation XML file to activate their server installation via the Strategy Licensing Site, the activation process fails with the following error:
Invalid XML file

CAUSE
This can be seen in cases where the Activate.xml file is corrupted. If users wish to investigate the exact nature of corruption in the file, contact Strategy Technical Support with the Activate.xml file.
ACTION
Re-generate the Activate.xml file using Strategy License Manager and upload the new file to the licensing website. If the issue is not resolved with this action, delete the existing Activate.xml file from the Strategy Intelligence Server machine and re-generate the file using Strategy License Manager.
