After installing ArcGIS Pro 3.5, updating to 3.5.2, and adding deep learning essentials (all without errors), I attempted to clone the <SPAN>arcgispro-py3</SPAN> environment. However, I received an <SPAN>InvalidArchiveError</SPAN> along with messages about a missing file.</P><P>Any suggestions on how to resolve this?

Updating the registry setting to enable long path support (<STRONG>LongPathsEnabled</STRONG>) resolved the issue.</P><P>Hope this helps others who might run into the same problem.</P> Sun, 29 Jun 2025 20:22:40 GMT https://community.esri.com/t5/arcgis-api-for-python-questions/issue-cloning-arcgis-pro-3-5-2-python-environment/m-p/1628114#M11483 Muhammad_Elbagoury 2025-06-29T20:22:40Z
