Issue Cloning ArcGIS Pro 3.5.2 Python Environment - InvalidArchiveError

Muhammad_Elbagoury

Hi all,

I’m encountering an issue while trying to clone the ArcGIS Pro 3.5.2 Python environment using the Package Manager on a fresh Windows install. After installing ArcGIS Pro 3.5, updating to 3.5.2, and adding deep learning essentials (all without errors), I attempted to clone the arcgispro-py3 environment. However, I received an InvalidArchiveError along with messages about a missing file.

Any suggestions on how to resolve this? Could it be a corrupted installation or a permissions issue? Thanks for your help!

I wanted to provide an update that the issue is now resolved.

Although ESRI's documentation mentions this problem as affecting version 3.1 and earlier, I encountered it while using version 3.5.2. Updating the registry setting to enable long path support (LongPathsEnabled) resolved the issue.

Hope this helps others who might run into the same problem.
