Error: Not a valid win32 app

[Unknown]

I just uploaded a table into Power BI, but when I try to apply the changes the following error message appears: "Failed to save modifications to the server. Error returned: 'The following system error occurred: %1 not a valid win32 app'".
Does anyone not what the problem might be?

Thanks

Hi @Unknown ,

May I know where did you get this problem? Power BI Desktop or Power BI service? Did you get this issue when you apple the changes in Power Query Editor? Could you please provide more details to make it more clear? Thanks~

In addition, here are some links may help you.

Hi,

I am facing the exact same issue in powerBI desktop.

After making any changes in powerBI query editor, when i try to apply those changes i receive the error:

failed to save modifications to the server. error returned: 'the following system error occurred: %1 is not a valid win32 application. '.

I have re-installed the app multiple times. But still the same error.

@Alchemist
Where are you installing your app from?
I was getting this error because I was installing it from the Microsoft Store. I deleted it and installed it from the link on the Power BI website and that fixed the problem for me.

I hope this helps.
