(IMW) warning: Re-index failed. () . . . Is someone else accessing this database?
Can’t re-index after installing latest version of IMW. Warning (see summary) indicated.
This error can occur if a re-index is attempted with one or more schematic diagrams displayed. If however, it happens just after an install it is more likely to be a corrupt or incorrect user list (e.g. In networked situations, there may have been multiple users, and now the installation is stand-alone).
In case 1, close all schematic windows to re-index. In case 2, via the menu: UtilitiesNetworkReset User List. Close all windows, answer affirmative to the prompts, then re-index.
