Hey there,
This sounds like it may be because of an issue with the network adapter installing, please find info on that here:

specifically their 2nd half;
Hamachi network adapter not displayed in Network Connections
Sometimes Windows fails to properly add the network adapter when told to install it. This can manifest itself in a scenario where there is no Hamachi adapter listed in the Network connections folder.
Manually reinstalling
- Go to Start > Run, and type hdwwiz (if running Windows XP, type: hdwwiz.cpl)
- If it beings searching immediately, let it finish, then choose the option Yes, I have already connected the hardware.
- If it displays the currently installed devices, please scroll down to the bottom and choose Add a new hardware device. If it is not there, skip to the next step.
- Choose Install the hardware that I manually select from a list (Advanced).
- Now select Network Adapters.
- Choose Have Disk, and Browse.
- Browse to Installation Folder, and select the Hamachi.inf file.
- Finish the install of the adapter.
- Once the install is complete, check your Network Connections folder and see if Hamachi's adapter is called "Hamachi", and not something like "Local Area Connection 4". If it is not named "Hamachi", rename it to Hamachi and try running the application again. Make sure, the Network Connection Hamachi is activated.
and let me know if you have further issues
