ArcGIS Pro 3.0 is having issues opening existing projects

Last Published: September 27, 2022


ArcGIS Pro is not opening existing projects, and elements such as maps or layouts appear blank, or the program takes too takes long opening them or they do not load.


  • The Microsoft Access Database Engine 2016 Redistributable 64-bit is not installed on the machine.
  • Microsoft .NET Desktop Runtime version 6.0.5 or later is not installed.
  • In some cases, projects may not open that have data in an incompatible version of Excel. Depending on the version of Microsoft Office, it may be necessary to perform a silent install of both 32-bit .NET Runtime and 32-bit Access DB driver, or sometimes one or the other, see the Guide to connecting to Excel files in ArcGIS Pro.
