You may have an RME audio device installed. If you do, turn off your network ports before you install MaxMSP. Then turn them back on again after you are done. One way to easily turn off your network ports is by disconnecting your ethernet cable or turning wireless networking off.
Look for a file with
the name "fireface_mme.dll". It should be found in the
‘..windowssystem32’ directory but it may be useful to perform a complete
system-wide search for this file. Move it out of the folder it is in, or rename it. Then try and install Max. Then you can move the file back to its original position.
Incidentally, RME have updated their driver not to include this file anymore.
