Does anyone know how to repair ArcGIS 10.3.1 installation without the original install package (or how to get it)?
I am encountering the "invalid pointer" script issue when using Geoprocessing tools (error described here: Fixing Script Error Invalid Pointer from ArcGIS Geoprocessing Tools? - Geographic Information Systems Stack Exchange or here: arcgis desktop - Script Error 'Invalid Pointer' in Spatial Analyst Tool - Geographic Information Systems Stack Exchange) and using Repair installation tool from the Windows programs menu seems to be the only solution, according to the forums.
The problem is, I need a valid setup.msi file in order to finish the repair process. I no longer have the installation package on my computer and I can't find it available for downloading. Is there any way to obtain it, or any other solution?
