I have this problem where I can't install or uninstall Hamachi cause it always has a pop up that says a previous version is already on my computer. Yet when it tries to update, an error comes up telling me that it failed and to contact technical support. I've been looking for a working solution for weeks. I've gone through regedit and gotten rid of all the entries named anything like Hamachi or Logmein, anything with those names, apart from the files under the subfolder "Net" which won't delete. I've gotten rid of the Network Adapter that was in my Device Manager and deletes all of the files I can possibly find, yet it always says I have a previous version on my computer. Help, please!
