PETROG 4 upgrade

Please download the relevant PETROG executable for your camera and system architecture (32 bit or 64 bit). Each release download has a file readme.txt to give you instructions on how to upgrade - if you are unsure of what to do and want to see that first then click here.

Note : from version 4 requires a licence key to run PETROG or it will only run in demonstration mode. Licence keys will be sent out to users to all users with current maintenance and support contracts, but if you have not yet had one, or have forgotten your key then please contact us.

PETROG 4 supports the following Windows operating systems: Windows 10 and Windows 7. On Windows 10, it does not run under the Metropolitan interface, only the desktop. It should run under Windows 8/8.1 and Windows XP but we no longer support these platforms.

 Important : This page is for upgrading from an earlier version of PETROG 4. For a new installation of PETROG 4 including upgrading from version 3 then go here
