You can temporarily disable ProjectWise integration using the Disable Integration button on the ProjectWise tab in your Office application.

This lets you quickly suspend integration, without having to turn off the feature entirely through the ProjectWise Explorer installer. As soon as you click Disable Integration, integration is disabled and the name of the button changes to Enable Integration. When you are ready to resume integration, click Enable Integration.

If you disable integration and then close the Office application, integration remains disabled for this particular application the next time you open it. Also, if you try to open an Office document from ProjectWise Explorer into an Office application that you had disabled in this manner, you are prompted to re-enable integration and open the file.
