Frequently asked question

Do I need to use regedit.exe or regedt32.exe to edit the Windows registry to work with or fix ArcGIS?

Last Published: April 25, 2020


No, using either of these tools to edit your registry is dangerous because you can inadvertently delete or change keys and values. Neither of these tools has an undo feature, and their user interfaces are not designed for editing safety.

ArcGIS comes with several utilities to allow you, in conjunction with Windows tools, to safely register or unregister components and functionality for ArcGIS. Failing to use these tools may result in improper or corrupted registry keys and values that will likely cause ArcGIS applications to behave erratically. For example, you can use the ArcMap Advanced Settings utility to set many options which are not available in the ArcMap user interface.
