flexlm | Shell script for license management | Monitoring library

Please note that I initially created an installer for two applications based on https://nsis.sourceforge.io/Two_installations_in_one_installer where the first application is the main one while the second application is the license manager. That said, I did remove the nested checkboxes with only one layer of checkboxes. FYI, I have also been referencing this article: https://www.codeproject.com/Articles/24187/Creating-an-Installer?msg=5782957#xx5782957xx

The issue that I am having is that when I run the installer, all of the files from MyApp and FlexLM are installed in the $PROGRAMFILES64\${PRODUCT_NAME} folder and in the C:\${FLEX_DIR}. So when I am installing two applications, it looks like both SEC1 and SEC3 are executed for the MyApp installation and both SEC1 and SEC3 are executed for the FlexLM installation:

The issue that I am having is that when I get to the second license manager app, where I click to browse for a custom folder, and create a new custom folder, when I press OK on the browse it then returns with this custom folder but then appends the application name after that. So for example when I return from the browse for custom directory dialog, it would not return with, say:

Sometimes I loose a toolbox license while running a MATLAB simulation taking several hours. The simulation then stops, I get an error message like:

• License checkout failed
• License Manager Error -5
• Cannot find a license for Communication_Toolbox.

but there is no red error-text you normally get when there's an error in the MATLAB code itself.

Since this license error is not reproducable easily, does anybody know if it is an exception that can be caught within a try/catch? I could then maybe catch it, check the error-message for the word 'license' and keep trying until I get a license again and continue.

Edit: what apparently happens is that every couple of hours the flexlm license server is reset, if someone else then grabs a license before my already running script does, then my scrip is aborted. Or maybe my script tries to check the license while the license server is restarting...
