AstroGrep

For managed AstroGrep Windows updates, close the application before launching the installer. The EXE x86 package can return Exit Code 0 while leaving binaries unchanged when AstroGrep is open, so use a pre-close, user-deferral, or conflicting-process step, then rerun detection and verify the installed binaries/version rather than relying on the exit code alone.

Close AstroGrep before applying a managed update. An update run while AstroGrep is still open can return exit code 0 even though the installed binaries were not actually replaced, so treat the running app as a conflicting process rather than relying on the process exit code alone.

For managed AstroGrep updates, close AstroGrep before launching the installer. If AstroGrep is open, the installer can return success while the binaries are not updated; close the app first and verify the executable version after setup exits.
