Hey, FIRST: change your LogMeIn Hamachi Tunneling service BACK to Automatic Startup (General Tab), Log On As Local System Account (Log On Tab, chk Allow service to interact with desktop." Next: Goto c:\Program Files (x86)\LogMeIn Hamachi. Right-click on hamachi-2.exe (this is also the LMI H Service) and open Properties/Security Tab. Look at the Users Group/Principle. Ensure that the parameters are set to "Read & Execute". REMEMBER, computer security will ALWAYS default to the highest restriction (eg: YourPC\you (your user account) is at Full, and the Users group is set to Read Only. Result: You can only read the file, nothing else. Post back to let me know what's happening.
If you are on a PC, open up a command prompt in admin mode and type
NET START hamachi2svc. Then, while still in the admin command prompt, go to the hamachi directory (cd "C:\Program Files (x86)\LogMeIn Hamachi\" and type (without typing "start"): hamachi-2-ui.exe. Or, you can download this script I made, and paste the file into your startup files, or start manually. But it must ne done via admin Start Hamachi
It appears a few of the automatic startup settings for logmein have changed or have become blocked as a result of windows updates. I will have a more permanant solution soon.
