Hi @Domantas,

Minimum requirements to install the Power BI desktop is .NET 4.5. Please check what's the version of .NET Framework in your machine follow this article.

If the version of .NET Framework is not the matter, please try the Microsoft .NET Framework Repair Tool to repair .NET Framework.

If issue persists, please try to enable the desktop trace file then share the trace file with us during the time that error throws our.

It seems that my NET Framework is the right version:

But how is that relevant? Everything was working fine with the older version of PowerBI Desktop and the issue started to appear only after the upgrade. So isn't this issue solely related with April update itself?

I can confirm the same problem with a user at my organizaiton.

April update throws the same error when trying to access options, or even trying to access "about" info.

[under_scores]

Should have confirmed - our organization is also on .Net 4.5.

Kindly try to reset your system datetime setting. it's work for me.

@Domantas@under_scores Please enable the desktop trace file then share the trace file with us during the time that error throws out.

Also there is a new April desktop version 2.45.4704.722 released on 4/17/2017. Please try this version to see if the same error occurs.

Thank you @nipun_khant007, your suggestion worked! Our datetime setting for our corporate build is set to yyyy-mm-dd. I tried the reset, and can confirm when set to M/d/yyyy, Power BI options are accessible again. Soon as I try changing my time back to yyyy-mm-dd, the error occurs again.

Appreciate the heads up @v-qiuyu-msft about the new release. I tried installing, can confirm that I'm on 2.45.4704.722 via add/remove programs, but same error when I'm on a datetime setting of yyyy-mm-dd (which our whole company is).

Hi @under_scores,

Please enable the desktop trace, then use the same steps to reproduce the issue. Share the trace file around that time the error throws out here.

Sorry, but I cannot figure out what is this trace file and how to make it. Would it be possible to get some guidance?
