Not all built MODS are compatible with all versions of Spotfire.

On the TIBCO Community published MODS there is a section on compatibility details. (with respect to Spotfire version information)

For example, This Pareto chart MOD is compatible form Spotifre version 11.5 and later , opening this MOD in version 11.4 will throw an error 

All Supported Environments

The reason for this is, that each mod code is based on a specific MOD API version that is public at the time of MOD development and that is compatible with the Spotfire version at hand. 

This apiVersion is defined in the mod-manifest.json in the MOD project.

For example, the code for the Pareto chart MOD on the TIBCO community is based on the MOD API version 1.3  that was introduced in  Spotfire 11.5. Hence It’s not expected to work on Spotfire 11.4 or earlier.
