I can't join my home group. I got the message "Windows cannot set up homegroup on this computer" then I had entered the password and trying to join. Things that I had tested: Remove idstore.sst in folder Windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking and rebooted computer Checked the password so it' correct. Run the trouble shooter (got notice about to check my time and date so it's correct). Tested change account name then I using same name (Niclas) and rebooted computer Re-create homegroup and re-join. Have test create and join the homegroup on booth of my computers. Any idea what it's wrong?

Did you try creating the home group from the other computer?

Try the old fashion way like in Vista and create a workgroup. All computers can interact in the same workgroup eq printer and file sharing. even remote desktop wil work. In RC7 the workgroup is not standard created. It can be chanched in the system tab.
