Licensing error -1007 (Manual license activation fails)

Symptoms

I pasted my hostid and tried to activate but the answer was:

Oops. Something went wrong. Please try again or contact us.

Error creating license. status=-1007 Invalid hostid type

Cause

If the hostid is a disk serial number, it is listed in BricsCAD like this:

disksn=OCZ-U43M095U73BO3T5D

If you use only the part OCZ-U43M095U73BO3T5D on the website, you will get this error.

Solution

You have to paste the complete hostid, including the prefix disksn=:

disksn=OCZ-U43M095U73BO3T5D
