Before DicomObjects can be used on any machine (physical or virtual), a list of unique MachineIDs is generated and used in the licensee activation process.
To generate a machine ID that can best (uniquely) identifies a machine, we gather various system information, for example:
Adding new hardware would not break the installed DicomObjects licence, as long as the existing hardware remain.
Removing or replacing existing hard drive, network card or upgrading existing Operating system will very likely kill the installed licence as the MachineID
Windows update is very unlikely to change the machine, therefore the existing licence remains valid.
