Problem updating Polyspace to R2019a Update9

Hello,

I face a problem documented here: Bug Reports 2052543 , when I run Polyspace I always get into that error. Based on the description there I have to update to R2019a Update 6. I downloaded version R2019a Update 9 (18 Sep 2020), installed it but nothing changed in the Polyspace version. Moreover, the bug I faced is still present. I am really confused why I download a version, install it and nothing changed.

Answer from AI:

There is a very common reason why your Polyspace version and the bug didn't change after installing the update: MathWorks products often install updates into separate directories, or they require you to manually refresh the integration between MATLAB and Polyspace.

If you just run your usual shortcut or launch Polyspace from MATLAB, your system is likely still pointing to the old, un-updated installation folder.

Here is how you can verify and fix this issue:

1. Check the Installation Path and Launch Directly

By default, MathWorks installers sometimes create parallel directories or don't overwrite the primary executable that your desktop shortcuts point to.

• Navigate directly into your file explorer to where you installed Update 9 (usually under C:\Program Files\Polyspace\R2019a\ or a specific update subfolder).
• Look for the bin folder and launch polyspace.exe directly from that folder.
• Go to Help > About Polyspace in the top menu. If it says Update 9 there, your installation was successful, but your system shortcuts are simply pointing to the wrong place. You will just need to recreate your desktop/start menu shortcuts from this executable.

2. Re-link Polyspace with MATLAB (Most Likely Cause)

If you are launching Polyspace analyses directly from the MATLAB command line or Simulink, MATLAB is still pointing to the older, bugged version of Polyspace. You need to manually update the connection.

1 Close all Polyspace windows.

2. Open MATLAB as an Administrator (Right-click the MATLAB icon -> Run as administrator).

3. Run the following command in the MATLAB Command Window to break the old link:

matlab

polyspacesetup('uninstall')

4. Change your MATLAB directory to the new Update 9 Polyspace folder:

matlab

cd 'C:\Program Files\Polyspace\R2019a\toolbox\polyspace\pscore\pscore'

(Note: Adjust this path if your Update 9 was installed to a different custom directory).

5. Run the installation setup command to link MATLAB to the updated version:

matlab

polyspacesetup('install')

3. Clear the Analysis Cache

Bug 2052543 can sometimes leave behind corrupted temporary files or metadata. Even after updating the software, Polyspace might try to read old, cached build data and throw the exact same error.

• Before running your next analysis, delete your project's previous results folder (usually named bf_results or similar).
• Clear the global Polyspace cache, which is typically located in your local AppData folder (e.g., C:\Users\<YourUsername>\AppData\Local\MathWorks\Polyspace\).

I installed this new version in exect the same folder as the old one. I start polyspace from polyspace.exe and still I get the old version. I suspect there is a problem with the installer, despite it is written on website Update 9 most probably it is not. Can be the case that the license administrator set a certain version for R2019a and no matter what update you select in the end you will download the base version?

Thank you for your help. Ok, I created a ticket, unfortunately at Mathworks versioning and installer for a specific patch are really chaotic topics. Unbelievable how complicated and disorganised mechanism they have.

Hi,

Based on your description, there might also be a case where the update was not cleanly installed. As a initial troubleshooting step, do the following:

Check the version of the current update:

To know the version of the current update, check the file <Polyspace_install_folder>/VersionInfo.xml.

Try installing the update again:

To install an update, two scenarios:

For an installation done using the network:

• Close all open Polyspace sessions
• Launch the update installer binary located in <install_folder>/bin/<arch>. This is named "update_installer.exe" for MATLAB R2019a.
• Follow instructions in popup. The installer will show the current update available.
• Update log is available in %TEMP%\mathworks_%username%.log

For an offline installation :

• Download update package from downloads page (https://www.mathworks.com/downloads/web_downloads/), then choose the release you need and then "Get Update Package for Offline Installation" and finally click "Download"
• Run update installer binary from command line with the -updatepackage flag.

For example:

update_installer.exe -updatepackage package_folder

package_folder is the full path to the folder where you unzipped the update package. The update installer runs silently and does not output any messages.

Something is really wrong with how they handle updates. I download from their Website a specific version(Update 9 - 18 Sep 2020). I look in the archive downlaoded and I see an older version. Unbelievable! I don't understand anything.
