I am trying to uninstall ArcGIS 10.3.1 for Desktop from Windows 7 SP1 using Uninstall a program and I am receiving an error message (pictured below):
Error 1325. EsriPyFldr is not a valid short file name.
The error message dialog appears just after:
Computing space requirements
seems to complete.
If anyone else has encountered this, then have you been able to find a way to get past it and uninstall ArcGIS 10.3.1 for Desktop?
My machine has what I would call a vanilla install of ArcGIS 10.3.1 for Desktop and ArcGIS Pro 1.1.1 so there are Python versions 2.7.8 and 3.4.1 as a result. ArcGIS Earth Beta is also on the machine.
I have made a posting on the same issue to https://geonet.esri.com/message/575655#575655
After running this utility (https://support.microsoft.com/en-us/mats/program_install_and_uninstall) unsuccessfully (it hung for two hours before I killed it) the error message when trying to uninstall shifted to:
This action is only valid for products that are currently installed
ArcMap 10.3.1 continues to start fine and doing
wmic product where "Vendor like '%Environmental Systems Research Institute%'" get Name, Version, InstallDate, InstallLocation
in a DOS window (at the suggestion of @MattWilkie) reports only the presence of Python 3.4.1 for ArcGIS Pro, ArcGIS Pro and ArcGIS Earth on my machine.
wmic product where "name = 'ArcGIS 10.3.1 for Desktop'" call Uninstall
but it just reported that there wasNo Instance(s) Available
. I'm a little reluctant to mess with my Python installs because I have 2.7.8 and 3.4.1 working nicely on the same machine with ArcGIS Pro and ArcGIS 10.3.1 for Desktop (which continues to work despite claims that it is not on the machine). I think I'll put it formally into local support's court tomorrow if I am still stuck then.
