PowerBi desktop update do not work

[giroldoale]

I just updated to the latest version of PowerBi desktop.

I have developed a complex report for my company, now for the first time I am unable to open it.

How can I downgrade PowerBi Desktop?

@giroldoale , you should be able to uninstall it using Add Remove program/app

and then you can download and install previous versions

Thanks, I'll try this solution. 
What could be the reason why a model entirely build with PBI, no external plugin, nothing not standar, wouldn't be openable with a release of PBI?
In order to build and maintain a stable solution for an enetrprise use how can avoid this type of issues?
Do you suggest to test an update with a different PC where a pdate PowerBI and test all current resports?
