What this fix does
Use these steps to stop ArcGIS Pro from trying to connect to a deprecated license server. This fix switches you to Named User licensing, which means you sign in with your Middlebury institution account instead of using a license server. Further documentation can be found in ESRI's knowledge base.
Warning: Editing the Windows registry can affect your computer if done incorrectly. Follow each step exactly and change only the items listed.
Step 1: Close ArcGIS Pro
Quit ArcGIS Pro completely.
Do not leave it running in the background.
Step 2: Open the Windows registry
Open the Windows Registry Editor.
Step 3: Navigate to the ArcGIS Pro licensing keys
Go to one of these locations in Registry Editor:
- HKEY_LOCAL_MACHINE > SOFTWARE > ESRI > ArcGISPro > Licensing
- HKEY_CURRENT_USER > SOFTWARE > ESRI > ArcGISPro > Licensing
Only one location may exist on your computer.
Step 4: Change or remove license values
Look for these values in the Licensing folder:
- LicenseType
- ARCGIS_LICENSE_HOST
Take these actions:
- Change LicenseType to NamedUser
- Clear the value for ARCGIS_LICENSE_HOST so it is blank
Do not edit any other values.
Info: You may still see a loading spinner after this change. This is expected and does not mean the fix failed.
Step 5: Reopen ArcGIS Pro and wait
Open ArcGIS Pro.
Wait until the loading spinner in the top-right corner stops.
When the screen finishes loading, the License type drop-down becomes active.
Step 6: Select Named User licensing
Open the License type drop-down.
Select Named User License.
Wait again while ArcGIS Pro processes the change.
Step 7: Sign in with your institution account
When the sign-in window appears:
- Enter middlebury for the ArcGIS organization's URL
- Click continue
- Sign in with your Middlebury account credentials
ArcGIS Pro should now open normally when sign-in completes.
