Releases of PETROG version 5 can be downloaded here by those users who have purchased it. These downloads will require your username and password to access. If you do not have a username and password, you can contact us to enquire about one. If your existing username and password do not work then you have not upgraded to version 5.

PETROG 5 supports the following Windows operating systems: Windows 10 and Windows 11. Earlier Windows platforms are not supported and we recommend that you do not install or use PETROG on them.

PETROG 5 requires a new licence key. The PETROG 3 or 4 licence keys are not sufficient.. A licence key is tied to a particular stepping stage serial number. If you have not been given a licence key or cannot find your licence key then please contact us to request one and include the serial number of your stepping stage’s control box (found on the underside of the control box and displayed on screen when PETROG runs).
