This error message suggests that the activation program is having difficulty reading your system's Host ID. Below are some possible workarounds:
Most likely, there is a permissions error which is preventing the activation software from properly reading the system's Host ID during the activation process. Manually starting the activation process with administrative privileges, possibly in "compatibility mode", might circumvent this problem.
For some reason, the activation program is having difficulties working on the machine. A workaround is to use an offline activation.
