The error code 0x00000573 translates to ERROR_LICENSE_QUOTA_EXCEEDED. This error indicates that the software you’re trying to activate or use has reached its maximum allowed number of licenses. There are two main scenarios where you might encounter this error:

1. Commercial Software Licensing:

• Many commercial software products are licensed per user or device. If you try to activate the software on more machines than your license permits, you might encounter this error.

2. Trialware/Freemium Software Restrictions:

• Some trial versions or free editions of software limit the number of users or devices that can use them simultaneously. Attempting to exceed this limit can trigger the ERROR_LICENSE_QUOTA_EXCEEDED error.

Troubleshooting Steps:

The solution depends on how you’re exceeding the license quota:

If it’s Commercial Software:

1. Verify License Agreement:

   • Check your software license agreement or purchase documentation to see how many devices or users your license covers.

2. Deactivate Unused Installations:

   • If you’ve installed the software on more devices than your license allows, deactivate it on machines where you no longer need it. This should free up a license slot for your current machine.

3. Contact Software Vendor:

   • If you’re unsure about your license terms or need to upgrade your license to accommodate more users, contact the software vendor directly. They can help you understand your options and purchase additional licenses if necessary.

If it’s Trialware/Freemium Software:

1. Review Software Limitations:

   • Refer to the software’s documentation or website to understand the limitations of the free or trial version, specifically regarding user or device limitations.

2. Upgrade to Paid Version (Optional):

   • If the free tier doesn’t meet your needs and you require more users or devices, consider upgrading to a paid version of the software that offers increased license quotas.

3. Explore Alternative Software:

   • There might be alternative software solutions with more generous free tiers or licensing models that better suit your requirements. Look for open-source alternatives or freemium options with higher user allowances.

Additional Tips:

• Always keep track of your software licenses and how many devices they cover.
• Manage software installations across your devices to avoid exceeding license limitations.
• Consider using a license management tool if you manage multiple software licenses for your organization.

By following these steps, you should be able to identify the cause of the ERROR_LICENSE_QUOTA_EXCEEDED error and take corrective measures to activate or use your software within the allowed license parameters.
