After a new version of the vault has been installed, you can update the clients (both SolidWorks and SolidWorks Explorer clients). No service pack is required.
When the vault is updated and you log in to a client (SolidWorks or SolidWorks Explorer), a message indicates the client is not compatible with the version in the vault if the client is not in the same major release of SolidWorks Workgroup PDM. (However, the service pack levels do not have to match. For example, you can run an SP3 version of the vault software with a client that has SP2 installed.) Follow the on-screen instructions to update the clients.
To update the client:
A pdmwUpdater dialog box appears and prompts you to close the client.
With the pdmwUpdater dialog box still open, close the client.
In the pdmwUpdater dialog box, click OK to confirm the update.
After the update is complete, click OK again.
The Login dialog box appears for you to log back in to the client.
