Add-in/Macros Security, Environment, Options Dialog Box
Use this page of the Options dialog box to define security settings for add-ins and macros in the integrated development environment (IDE). You can access the Options dialog box by selecting Options from the Tools menu and then selecting the Add-in/Macros Security page in the Environment folder.
Administrators can prevent users from changing these settings. For more information about macros security, see Macros Security and Sharing Issues. For more information about security for add-ins, see Add-In Security.
You must restart Visual Studio for any changes made to these options to take effect.
Avoid clearing the Allow Add-in Components to load checkbox in the Add-in/Macros Security options page when running Visual Studio 2008 on Windows Vista. Doing so causes the IDE to hang.
