If you already have a demo key installed in your computer and it is still valid, you have to delete it completely from your computer before activating the new demo key.
Here is what to do:
- Close EZMQC
- Delete “sensq.dat” and “sensors.dat” at C:\EasyMatchQC\Sensors
- Delete “hlsq.sys” at C:\Windows\SysWOW64\drivers (if you using the 64 bit system) or at C:\Windows\System32\drivers (if you using the 32 bit system)
- Open EZMQC and then use the new demo key to activate it.
