How to remove CAM Assist from Autodesk Fusion, Mastercam, GibbsCAM, Siemens NX or SolidCAM, for example before a clean reinstall. Your machines, materials and tool libraries are stored in your CloudNC account, so uninstalling doesn't delete them.
Before you start
- Close your CAM package, and make sure CAM Assist isn't running.
- Uninstalling doesn't delete the CAM Assist log folders. See Find your CAM Assist log files.
SolidCAM
CAM Assist is part of SolidCAM, so it has no uninstaller of its own. It's removed when you uninstall SolidCAM, and installed again with SolidCAM. See How do I get CAM Assist in SolidCAM?.
Run the uninstaller
Every CAM package uses an uninstall.exe in the CAM Assist install folder. In File Explorer, paste the folder path into the address bar, then run uninstall.exe.
| CAM package | Install folder |
|---|---|
| Mastercam | C:\Users\Public\Documents\Shared Mastercam <version>\Add-Ins\Cloud NC\ (for example Shared Mastercam 2026) |
| GibbsCAM 2025 | C:\Program Files\Common Files\GibbsCAM Shared\Plugins\CAM Assist for GibbsCAM 2025\ |
| GibbsCAM 2026 and 2027 | C:\Program Files\Common Files\GibbsCAM Shared\Plugins\CAM Assist for GibbsCAM 2026\ |
| GibbsCAM, GovCloud | C:\Program Files\Common Files\GibbsCAM Shared\Plugins\CAM Assist for Gov Cloud for GibbsCAM <version>\ |
| Siemens NX (all versions) | C:\ProgramData\CloudNC\Siemens NX\Add-ins\CloudNC CAM Assist\ |
| Autodesk Fusion (Windows) | %AppData%\Autodesk\Autodesk Fusion 360\API\AddIns\CAMAssist\ |
If you use more than one Mastercam or GibbsCAM version, each has its own folder. Uninstall each one you want to remove. ProgramData and AppData are hidden folders, which is why pasting the path is easiest.
On a Mac, delete the CAMAssist folder from ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/AddIns.
Delete the install folder for a clean reinstall
After uninstalling, delete the install folder from the table above. This makes sure nothing is left over before you reinstall.
If Windows won't let you delete it, the folder was probably created with administrator permissions, or a program is still using it. The uninstall has still worked, so you can carry on.
Reinstall
To reinstall, download the latest installer from the CloudNC download page, close your CAM package and follow the install article:
- Install CAM Assist for Autodesk Fusion
- Install CAM Assist for Mastercam
- Install CAM Assist for GibbsCAM
- Install CAM Assist for Siemens NX
If the installer fails, look for install-log.txt in the install folder (the same folder as uninstall.exe) and send it to CloudNC support.
When you start CAM Assist again, sign in with the same email. Your preferences (units, theme, language) are stored on the computer, so you may need to set them again. See Where does CAM Assist store my settings?.
