HDF5 mismatch issue

When I tried to run the analysis, in the cmd it says, version mismatch is there with the HDF5. It suggests a method to overcome the issue but it doesn't work. A screenshot is attached for more details. How to overcome this issue?

Can you try with a newer version of OpenSees?
In that old version, OpenSees links to HDF5 at runtime, so it's the user's responsibility to make sure to have a proper HDF5 library.
In the latest version, instead, HDF5 is directly inside OpenSees

Dear Team,

In the latest OpenSees version (3.7.2) it doesn’t contain the HDF5 library. Thats the main issue I had to use the OpenSees 3.4 version.

I changed the environmental variable to 1 and now the program works. I hope that doesn’t affect the results.

That's also fine.
It is simply saying that your versions are different. But you can safely use that environment variable because in the MPCORecorder we don't use the very latest features of the HDF5 library.
