I would like to know if anyone knows how to get this to stop happening, I am happy that it works onces restarting, but I would really like to not have to waste time with restarting and re opening the software.</P><P>Thank you for any help!<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="help.jpg" style="width: 999px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/139960i61140FA12DF85068/image-size/large?v=v2&amp;px=999" role="button" title="help.jpg" alt="help.jpg" /></span></P> Fri, 05 Sep 2025 22:58:16 GMT AndrewLundstrom 2025-09-05T22:58:16Z https://community.esri.com/t5/arcgis-geostatistical-analyst-questions/error-999999-something-unexpected/m-p/1648378#M1845 <P>Hello while using ArcGIS pro 3.4.3 (but has happened on many versions) while using Geoprocessing tools usually during interpolations but recently while using the 'Compute change raster tool' I will get this Error '999999 something unexpected' but if I close the software and reopen it the tool works.
