Today I attempted to upgrade ArcGIS Pro version 2.4 to 3.0.3 but kept running into error messages. I downloaded a new installation file from our organization's ArcGIS Online account and ran the installation, but it pauses halfway through with the message "Error 1303. Error reading from file C:\Program Files\ArcGIS\Pro\bin\ArcGISPro.exe". I checked and the "ArcGISPro.exe" file is confirmed in that directory. Is anyone else having this issue? Any help would be greatly appreciated, thanks!
