    Add-in Load Behavior

    When running add-ins in Office, problems with load behavior can occur. The add-in may not load (properly) or may even be completely disabled.

    Causes

    There are multiple causes for this, such as:

      • An incorrect path in the registry to the shared (config) and content folder
      • Manually disabled add-ins after, for example, an Office program crash
      • Aggressive disabling of (slow) add-ins by Office itself. This is particularly a problem in Outlook.

    Solutions

    To solve these issues, you can use various registry files. You have the following options:

    Always enable dStyle365 (force) in Current User.reg

      • Forces the add-in to be on, ensures that load behavior is ignored, and users can no longer uncheck the add-in via options->add-ins.
      • Applies only to our add-ins; others can be added by adding a line with the (internal) name of the other add-in.

    Via this link you can directly download the registry file to apply the setting.

    Or find the key at this location: C:\Program Files (x86)\Documentaal\[dStyle or LegalWord]\LegalWord\Binary\StockConfig\RegKeys\Always enable dStyle(force) in Current User.reg.

    Increase outlook loading treshold to 1388 (CU).reg

      • Sets the time Outlook gives add-ins to 5 seconds (instead of 0.5s), which precisely solves the problem below. This value can also be manually adjusted (1388 is hexadecimal, stands for 5000ms).
      • This applies to all add-ins! So if there are many slow add-ins, it may be advisable to disable some of them.

    Or find the key at this location: C:\Program Files (x86)\Documentaal\[dStyle or LegalWord]\LegalWord\Binary\StockConfig\RegKeys\Increase outlook loading treshold to 1388.reg.
