Install CAM Assist for Mastercam on a shared network folder

If your shop runs Mastercam from a shared Mastercam folder on a server, install CAM Assist into that shared folder and point each Mastercam profile at it. This article covers the install, the Mastercam data path, permissions and how to check it works.

For a normal install on one computer, see Install CAM Assist for Mastercam.

Before you start

• You need Windows administrator rights on each computer you set up.
• Every Mastercam user needs full read and write access to the shared Mastercam folder on the server.
• Use the CAM Assist installer for the Mastercam version you run (2025, 2026 or 2027). Each installer works with one version only.
• Close Mastercam on the computers you're setting up.

Remove an older version

If an older CAM Assist is installed, uninstall it first. See How do I uninstall CAM Assist?.

Install into the shared folder

1. Run the latest CAM Assist installer for your Mastercam version.
2. Install CAM Assist into the Add-Ins folder of the shared Mastercam folder on the server.

Point Mastercam at the shared folder

Do this on each computer, first in your own Windows user profile and then again in the administrator profile.

1. Open Mastercam.
2. Go to File > Configuration to open System Configuration.
3. Click Files.
4. Under Data Paths, select Shared Mastercam Folder.
5. Under Selected Item, set the path to the shared Mastercam folder on the server (the folder with your configuration files, tool libraries and machine definitions).
6. Click OK and restart Mastercam.
7. Sign out of Windows, sign in as an administrator, and repeat steps 1 to 6.

Check it's working

1. Signed in as the administrator, open Mastercam.
2. Open the CloudNC tab on the ribbon and click CloudNC CAM Assist.
3. If CAM Assist starts, sign in to Windows as the user and check it starts there too.

If CAM Assist doesn't appear

• No CloudNC tab: check the Shared Mastercam Folder path is the server folder you installed into, and that it's reachable from this computer. Then restart Mastercam.
• It works for the administrator but not the user: check the user's profile has the same Shared Mastercam Folder path, and that the user has full read and write access to the shared folder.
• The path can't be reached: check the network path and any access restrictions with your IT team.

For other start-up problems, see the "If the CloudNC tab is missing" section of Install CAM Assist for Mastercam.

Still not working?

If you've done all of the above, contact CloudNC support. Include the shared folder path, your Mastercam version, and the log files from %ProgramData%\CloudNC Ltd\CAM Assist\logs on the computer where it fails.
