When you run
isinteg -patch, it runs but it does not report an "Access is Denied" error message. Instead, it reports that the information store has been successfully updated. To confirm this behavior, rename one of the information store files, and then run the command line again. Isinteg does not report that it could not find the information store; it does not report any error messages.
For example, if you want to rename the Pub.edb file to "Pub.old", run
isinteg -patch. Isinteg reports that it has successfully updated the information store. However, you expect to receive the following error message:
Warning, public store was not found (assuming private-only store)
