Prognosis patches usually come with two formats, .exe and .gz, for example, z1190p02-win.exe and z1190p02-win.gz.
The exe format is for graphical installation, whilst the .gz format is for command line installation using irpatch.exe tool.
This is particularly useful when performing the patch installation from command line with a script.
Below are the steps to install a patch from command line:
1. Download and copy the z1190p02-win.gz file to the <Prognosis>\Patch directory;
2. Open a command prompt as Administrator and navigate to the Prognosis\Patches directory.
3. Stop the Prognosis Service by running the command: Net Stop Prognosis
4. Run the command: irpatch -i z1190p02-win.gz
5. After the patch installation is finished, run the command to start the Prognosis Service: Net Start Prognosis
