Download CCM Quantum
Use the CCM download page and save the current Windows installer somewhere you can find it.
Windows installation · Quantum 2.0.23
Install CCM Quantum on Windows without switching security protections off.
Verify the file first, keep SmartScreen and antivirus enabled, then follow the normal Windows setup flow. The current installer is unsigned, so an unknown-publisher message can appear.
Verify the file
Compare the filename, exact byte size and SHA-256 before you open the installer.
Open the installer
Double-click the verified file. Read any Windows SmartScreen or security message that appears.
Review the Windows prompt
The current installer is unsigned, so Windows cannot show a verified publisher identity. Keep SmartScreen enabled.
Complete setup
Follow the installer prompts, then open CCM Quantum from the Start menu or desktop shortcut.
Sign in and check access
Use your CCM account to view product access and launch TableSync when your annual access is active.
Why Windows may warn you
Unsigned means Windows cannot verify a publisher identity for this installer.
That is a limitation of the current release, not a reason to turn security off. The practical check available today is to download from CCM and compare the published file details before you continue.
- Use the current CCM download route.
- Compare the exact SHA-256.
- Keep Windows protection enabled.
- Stop if the values do not match.
