When pushing out a newer version of CAD software to the user can I just update or push out a registry key without having the user having to manually re run the idesktop integration (pwc.exe)
When pushing out a newer CAD version of software, in order for ProjectWise to integrate various registry keys are updated.
You can deliver the integration piece using Microsoft Installer Technology to pick up the integration which will update the various keys depending upon what CAD software you are installing. (see http://communities.bentley.com/products/projectwise/content_management/w/wiki/5497.aspx for details)
Keep in mind, if it is AutoCAD you may also have to install a new add on module. This is all dependent upon which version of ProjectWise and AutoCAD you are using.
Please note: Installation issues with ProjectWise using the Microsoft Installer Technology are handled by a company's IT department or Bentley Professional Services
