Apply executable and restart your computer. Run the specific Hotfix Patch executable file.
While SP12 serves as the base version, Schneider Electric has released subsequent hotfixes (such as ) to address specific field issues and security vulnerabilities. These patches are often critical for:
Patches an issue where extensive alarm logs or recipe transfers could overflow the HMI runtime memory and cause panel reboots. Step-by-Step Installation and Patching Process
The patch may reset driver parameters to default values.
Resolves sudden software crashes when compiling large, tag-heavy projects.
If you are running an older service pack, execute the SP12 installer first. Do not attempt to apply a hotfix directly to a lower service pack version, as this will corrupt the software binaries. Restart the computer following completion. Step 2: Apply the Cumulative Hotfix
After patching the development software on your PC, you must update the runtime firmware on the physical HMI panels. Connect to the HMI via Ethernet or USB, and perform a full project download. Select when prompted to push the patched firmware to the machine. Troubleshooting Common Patching Issues Root Cause Error: "Base version not found" The hotfix is being applied to SP11 or older.
Updating industrial software can sometimes trigger environment conflicts or registration mismatches. Issue 1: "Installation Aborted - Invalid Version Detected"
In software terminology, a Hotfix is a critical, incremental update released outside of the normal scheduled patch cycle. It is usually created to solve a specific, urgent customer problem.
Downloaded hotfixes typically arrive as a compressed archive ( .zip ). Extract the files completely to a local directory (e.g., C:\Temp ). Avoid running the installer directly from inside a zipped folder.
Execute the specific hotfix executable file (typically delivered as an .exe or via the Schneider Electric Software Update tool). The installer automatically detects the SP12 directory pathways and replaces outdated .dll files and runtime drivers. Step 3: Verify the Installation Open Vijeo Designer. Navigate to the top menu and select > About .
After installation, go to Help > About Vijeo Designer . Verify the build number ends in .142 or the specific hotfix revision provided by Schneider support.
