Red Exclamation Points in the Table of Contents
Problem:
You open up your MXD to be greeted with a series of red assertion points in the Tabular array of Contents instead of your data drawing in the Display Window.
What Happened:
ArcGIS saved the path names from the machine you started your projection, and the drive directories referenced past those path names are non the aforementioned on the machine you are currently working on. For example, if you were working off an external hard drive at school, and the schoolhouse computer called it "E:", and so your abode computer calls that aforementioned bulldoze "F:", the path name volition be wrong.
How to Fix It:
Repair the Information Source
Locates the data when ArcMap cannot find it. You will know it can't find information technology when the each layer name is proceeded with a cherry assertion point. Repair information source is greyed out the rest of the time.
 |
|
| This method should repair all of the data source errors at once. If not, you lot will have to practise it again until information technology finds all of the sources. | |
How to Foreclose information technology in the Time to come:
 | In the future, this error can be prevented by marking a box in the Map Document Properties to "save relative pathnames". This will "erase" the letter in the pathname, and the MXD volition look for information in the same identify as it did on the other machine, only skips the drive letter. |
Cannot [complete the activity you are request ArcMap/ArcCatalog to exercise] because it is in use by another awarding/user. Cannot acquire a schema lock because of an existing lock.
Problem:
Y'all are attempting to practice some action in ArcMap or ArcCatalog and you accept gotten a super "friendly" message that the action cannot be completed due to an existing lock.
What Happened:
ArcGIS works on a abiding cache system, meaning if a file is in use in one program (another ArcGIS suite software, Excel, Discussion...) it cannot be used/inverse modified in ArcMap.
How to Prepare it:
The only fashion to release the lock is to shut the offending program (the error won't tell you, but information technology'south whatever program yous're not currently using) and wait a minute or three for the programme to completely shut and the lock to be released. Then try your activity again. If it still fails, attempt closing all your programs, the relaunching ArcCatalog/ArcMap and try again. If it nonetheless fails, lastly, try opening a new, blank ArcMap session, adding the offending file, and try your action again.
- Note: If yous're working with joins/relates, this error may exist due to the fact you cannot edit joined data. Remove the join(s) then try your action again.
Geoprocessing Tools "Background Server Threw an Exception"
Trouble:
Y'all ran a tool from the ArcToolbox, and it failed. When yous bank check the messages (either by clicking the link in the "failed" pop up, or Geoprocessing Card > Results > + Current Session > +Tool Name > + Messages), the error code is a super helpful "Groundwork Server Threw an Exception".
What Happened:
The background server threw an exception! Duh! Only for existent, some function of the background processing failed when running the tool.
- Groundwork processing is a feature in ArcMap that allows yous to go along piece of work on your project while running tools in the background
How to Ready it:
Turn Off Background Processing:
 | Turn off background processing
|
How to Prevent it in the Hereafter:
The "background exception" error is striking or miss. In that location really isn't a "prevention". Sorry.
Assistance! I cannot open up the MXD I saved in the GIS lab at home!
Problem:
You've saved your MXD in the GIS lab, but when you try to open information technology at home, information technology gives an error that this file tin can only be opened with ArcMap 10.x.
What Happened:
ArcGIS is not backwards compatible, meaning, that MXD's created in an earlier version will open in a later version but MXDs created in a later on version will non open in an earlier version. For instance, 10.one MXD files volition open up in x.3, but 10.3 MXD files will not open in x.1.
How to Fix it:
 | Unfortunately, the simply way to prepare this problem is to become back into a later version of ArcMap and save the MXD to open in an earlier version. |
How to Prevent it in the Future:
In all cases where the goal is to open up an MXD in an before version of ArcMap, yous must save a copyearlier you lot close out of the later version. That is to say, earlier you leave the GIS lab where the computers are running ten.iii, you must offset "Salve a Copy" and designate the version you wish to relieve the MXD equally.
- If you are unsure of the version of ArcMap you (or someone else) may be using, information technology's okay to salvage equally ten.0, since ArcMap will upgrade files. But to avoid versioning problems in full general, endeavour to save the file in the target version.
- From the File carte du jour in ArcMap, utilise "Save a Copy"
- Designate the version from the dropdown under the MXD proper noun
- Be sure not to open up the file on the current machine, or ArcMap volition try to upgrade it (it should give yous a warning before it does, but just to be condom, don't open up information technology until y'all are on the target car)
Tool Non Licensed. Unable to execute the selected tool.
Trouble:
You lot attempt to run a tool, but when you click to open information technology, your presented with an error message stating the tool is non licensed and ArcGIS is unable to execute the selected tool.
What Happened:
Each extension in ArcGIS costs money beyond the base price of the software, and many schoolhouse and companies save money by non purchasing extensions they do not needor only purchasing a limited amount of licenses to exist shared on a network of several users. To allow anybody access to all of the licences, extensions must beenabled earlier tools within that particular toolbox can be launched. Enabling the extension checks it out from a central location and allows the tools associated with information technology to be utilized.
Think about it like a public library. Instead of purchasing tons of copies of 1 particular all-time-seller, they purchase a limited number of copies, so lend them out free of charge to their registered users. While the book is checked out, no one else can read it. ArcGIS extensions work the same fashion - the extension will merely work for the same number of computers for which the visitor or school has paid for until they are checked back in.
How to Gear up it:
To fix this error:
- note the extension which is disabled (in this screenshot, nosotros meet "There is no Spatial Analyst licence currently bachelor or enabled"
- shut the "Tool Non Licensed" pop-up
- enable the required extension
- relaunch the tool
To enable an extension:
- open the Customize menu
- click on "Extensions" to launch the dialog box
- place a cheque marking in the box to the left of the extension name
- close the Extensions dialog box
If the extension is not bachelor (not paid for or all the copies are checked out), instead of a check marking appearing in the box, a different popular-up will appear stating "There is nolicense name currently available"
How to Prevent it in the Time to come:
The simply existent "prevention" is to make certain the extension is enabled prior to trying to run a tool. This, however, is non a real "problem", it tin merely be annoying occasionally.
The ArcGIS Basemaps Volition Not Load!
Problem:
When yous use the dropdown to "Add Basemap", it is missing OR you lot've successfully selected a basemap only information technology will not load in ArcMap.
What Happened:
While it'southward hard to tell from here, information technology's most probable an internet or software problem.
How to Set it:
The get-go thing to try is: saving your MXD, launching ArcMap with an new, blank map, closing ArcMap, and opening your MXD over again. This most likely won't work, simply information technology's worth a try.
The adjacent affair to try is adding the basemaps as an ArcGIS Server.
How to Preclude information technology in the Future:
There really isn't anything you lot tin practise to prevent it, as information technology was near probable acquired by an cyberspace or software error. The only thing you can practice is make sure your connection is skilful, or use the ArcGIS Server Method.
Microsoft Excel File: Failed to Connect to Database. An underlying database fault occurred. Class not registered.
Problem:
You attempt to add a sheet from an .xlsx file (problem does not seem to occur with .xls files), and ArcMap gives an mistake of "Failed to Connect to Database. An underlying database error occurred. Class non registered".
What Happened:
ArcGIS sees Excel files equally database files (we learned they were data tables - of which database files are a blazon of data table), and is unable to read it. I don't really accept a very specific reason other than that. Sorry.
How to Fix it:
Install the 2007 Role System Driver: Information Connectivity Components
Close ArcMap (saving your .mxd, if needed). Visit https://www.microsoft.com/en-united states of america/download/details.aspx?id=23734 and download the commuter. Install it as you would whatsoever other .exe This commuter plug in doesn't require a restart. Restart ArcMap and endeavor to add the sheet once again. In that location shouldn't be an error this time.
How to Set up it in the Hereafter:
Once the plug-in has been installed on your reckoner, you shouldn't have the problem in the future.
