We have some reports of the *Windows only* MaxMSP 463 installer hanging on certain machines. If this happens to you, please try the following
Try disabling your Internet connection (be it by unplugging the Ethernet cable
or disabling a wireless connection) temporarily and then try running the installer again.
After this you can turn your network back on again. We shall include a permanent fix for this problem in a future release of MaxMSP for Windows.
If you are still stuck after this, please do not hesitate to get in touch with us at
