ActiveX Registration Options

Registration Location

Register ActiveX builds to HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER option. While modern applications use HKEY_CURRENT_USER, for VBx compatibility components must be registered to HKEY_LOCAL_MACHINE. Note that this requires running as admin when registering.

Build-Time Registration

Registration at build time is optional. The Register DLL after build setting in Project Settings lets you disable automatic registration, if for example you wanted to move the file first.

ActiveX registration describes what the IDE shows when a build registers a DLL, the warning for a project that registers to HKEY_LOCAL_MACHINE, and what Clean removes.
