Silently Install a Plant SCADA Patch

You can silently install a Plant SCADA patch by running a command from the command line.

To silently install a Plant SCADA patch:

1. After you have manually extracted the patch ZIP file, run the following from the command line (assuming the patch executable is in the current directory):

   "Plant SCADA 2026 Patch <n>.exe" /silent

2. Replace <n> with the patch number and date to match the name of the executable.

   This command will return immediately without waiting for the patch to finish installing.

   To wait for the patch to install (for example, when installing from a batch file), use the built-in start command:

   start /w "" "Plant SCADA 2026 Patch <n>.exe" /silent

   The empty "" are important to tell the start command to interpret the quoted patch name as the executable to run (instead of the window title). The quotes are required on the patch name as it contains spaces.

Any required prerequisites (for example, Platform Common Services) will be installed.

Any running Plant SCADA services will be automatically stopped by the patch install and restarted again when complete. Any other running Plant SCADA programs, such as Plant SCADA Studio or Plant SCADA Runtime in non-service mode, will not be stopped. If this occurs, the patch will not be successful.

Return Values

The patch executable will return 0 to indicate it was installed successfully.

If 3010 is returned, it indicates that the patch was installed successfully but a reboot is required to complete installation.

Any another non-zero value will indicate an error (see the table below).

Use the %ERRORLEVEL% environment variable to check the return code. The start command must be used to retrieve the return code properly.
