I ended up installing Pro from my machine and reinstalling 2.7 through the my.esri.com download, rather than the in-app upgrade option. It seems to be working now.</P><P>Definitely seems to be related to this post - wish I'd seen it first! haha</P><P><A href="https://community.esri.com/t5/arcgis-pro-questions/arcpro-2-7-warning-before-upgrading-failed-to-load-system-tools/m-p/1010858#M35195" target="_blank">https://community.esri.com/t5/arcgis-pro-questions/arcpro-2-7-warning-before-upgrading-failed-to-load-system-tools/m-p/1010858#M35195</A></P> Fri, 18 Dec 2020 18:07:03 GMT https://community.esri.com/t5/arcgis-pro-questions/i-m-getting-quot-error-000574-python-not-installed/m-p/1011012#M35217 Katie_Clark 2020-12-18T18:07:03Z https://community.esri.com/t5/arcgis-pro-questions/i-m-getting-quot-error-000574-python-not-installed/m-p/1011028#M35219 <P>A clean install provides the opportunity to get rid of other computer clutter as well&nbsp;<span class="lia-unicode-emoji" title=":beaming_face_with_smiling_eyes:">😁</span>.&nbsp; And renaming the folders in "Users" allows you to try out the install before deleting them.</P> Fri, 18 Dec 2020 18:21:27 GMT https://community.esri.com/t5/arcgis-pro-questions/i-m-getting-quot-error-000574-python-not-installed/m-p/1011028#M35219 DanPatterson 2020-12-18T18:21:27Z https://community.esri.com/t5/arcgis-pro-questions/i-m-getting-quot-error-000574-python-not-installed/m-p/1011036#M35220 <P>Good point, I'll remember that in the future!
