Handling Power BI error occurred - v. 2.78.

[Anonymous]

Hello,

I created a dashboard, save it and exported the template by Power BI Desktop last version (2.79).

When I send them to the client (due organizational policy cannot to install 2.79 , only corporative 2.78 feb 2020), two errors ocurring:

1 ) with pbix: Object reference not set to an instance of an object

2) with pbit: Failed to save modification to the server. Error returned MEngineHelper is not loaded

I replicated same OS version in another VM instance, same IE version, and original 2.79 works only same version, but 2.78 don't.

I removed three Viz apps, but errors still appears again.

How I can to figure out the problem on my VM ?
