I have the pro version (8.25 at the moment) and it tells me that version 8.4 is available but it will not install. I get a message that it can not replace zmmspro.exe (access denied). I have VISTA and it has been running fine. I did run the install file as administrator, I also renamed the zmmspro.exe file and it appeared to load the zmmspro.exe but then it errored on a dll.
Should I uninstall and reinstall the 8.4 or is there another suggestion since I am using Vista? Or should I just wait for the next point release to see if I have better results?
