Locator not supported

JoshWhite — Fri, 29 Mar 2024 21:00:44 GMT

I've searched this community time and time again and have never found a good solution. How do I get rid of the warnings when I open a pro project and it says locator not supported. It is a strange error and it continually loads bad locators even when I remove them and save. How do I stop this. Its clearly a hard coded bug because the aprx is apparently corrupt but how do I fix it?

Two things to try based upon Esri Support Services cases:

1. Log out of ArcGIS Pro and sign back in. In some cases, this fixes the issue.
2. Sometimes the *.aprx is referencing an unsupported locator, say 10.6. Find that locator and move it to a new location. Then start the *.aprx in question. Does the error message persist?

Logging out and signing back in seems to eliminate the error messages for now but the locators in question keep coming back. Currently they have the red exclamation mark next to them. I no longer use my own and just stick to the World Geocoding Service as it serves my needs.

How do I find the locators in Windows Explorer? I search for loc and lox files and the locators in question don't appear to come up in the searches. Maybe I'm searching in the correct directory though.

Sounds like we're getting there. So you can find the ArcMap locators in the following directory - C:\Program Files (x86)\ArcGIS\Desktop10.8\Locators - are there any there?

They weren't in there, only default ones so I guess I'm good to go there. The locators keep reappearing every time but they aren't causing the loading issues anymore. I'm going to go ahead and mark this as a solution but I may reopen if I run into any issues again. Thanks Robert!

Sounds great Josh - sorry we were not able to find these other locators but at least the warning message is no longer appearing. All the best!

I've been having this issue as well. I discovered (accidentally) that the locator references are also stored in the individual maps. I happened to get the "Maps" section expanded before the errors started and noticed that the locator errors would come in clusters, then pause. Additional maps would load during each pause,

after which the locator errors resumed.

I came up with a Python script to remove all the disabled locators from each maps definition. The assumption is that if the locator was enabled, it was valid, otherwise it wasn't supported. Of course, this would remove any locators that you manually disabled. So far, it seems to be working. It does not remove the unsupported locators from the project. That needs to be done manually. Be sure to save the project after running the script.

#get current pro project thisProject = arcpy.mp.ArcGISProject("CURRENT") #list all map objects maps = thisProject.listMaps() #find the "enabled" locators and assume all others aren't supported #replace locator list with enabled only for m in maps: mdef = m.getDefinition('V3') loclist = mdef.locators newList = [] for l in loclist: if l.enabled: newList.append(l) mdef.locators = newList m.setDefinition(mdef)

Interesting and thank for sharing the Python script as well! Josh - are you able to run the script to see if removes the invalid address locators?

Well, I tried but I don't really know how to run that. I don't have much experience running scripts. I pasted it into a python window and I have no idea if it did anything. I'm sure I'm missing something.

That should be all you need to do, and then just save after. To double check, you can try So far, it seems to have worked for me. However, I'm not quite ready to declare success. As you noted above, the notices don't seem to crop up every time the project is open. So it may be a false positive.

Yes I don't receive the notices anymore either but that stopped after I logged out and back in as Robert suggested. The rogue locators still come up but they don't seem to be causing any issues.

Using Pro 3.5.4 and I also have address locators with red exclamation marks that I've "removed from project" and saved it, but they keep coming back. I ran @JCGuarneri 's script and they're no longer in the maps either, but they keep coming back when I reopen the project. ~~No errors pop up luckily, it's just annoying to have broken items in the project.~~ I'm getting errors again.

Re: Locator not supported

JoshWhite — Fri, 07 Nov 2025 20:11:25 GMT

I do still periodically get the error messages especially after applying a new update. And yes, I hate seeing the broken items.

Still having this issue in Pro 3.6.2. Have to click through ~10 "Locator is not supported" messages to just open my project.
