FAQ: How does ArcGIS Desktop installation change the registry?

Question

How does ArcGIS Desktop installation change the registry?

Answer

ESRI does not document changes made to the registry during installation. The registry keys are created when the DLLs are self-registered.

If desired, it is possible to produce a list of the changes:

A. Export the registry before installing.
B. Install the software.
C. Export the registry after the installation.
D. Use a Kdiff tool to view the differences in the registry that were created before, then after the installation.
