Hi,

I'm trying to launch Power BI desktop app on my laptop without success.

The error pop-up says:

Unable to Start Power BI Desktop

We weren't able to connect to the model

Any help appreciated.

Are you trying to open an existing .pbix file, or start the program directly from its launcher?

Whichever one you're trying, try the other and let us know what happens.

I'm trying to do my 1st launch of app after downloading.

I don't have any file because I can't open the software to make one.

Well, I've tryed to open blank pbix with no success either.

"...corrupt or not a valid reort file".

So frustrating.

I have heard many reports on PBIX file been corrupted during save. There could be a number of reasons that leads to this. In order to address this issue, we are working on improving the IO reliability, as well as providing auto-save/backup functionalities.

For now, I would advise everyone to at least back up your PBIX files once per day if it's been actively developed on.

Have you ever changed your hosts (C:\Windows\System32\drivers\etc) file? Can you retry by setting your hosts file as default.

I also am not able to launch Power BI Desktop. My work PC which is 32 bit Windows 7 based system was updated yesterday and works fine. My home PC which is 64bit WIndows 10 wont launch. I've uninstalled and re-installed, dowloaded the latest version installed, un-installed and re-installed, even installed enterprise gateway as suggested in other posts all to no avail. any suggestion would be appreciated.

I have the same issue. I used Power BI for 5 months without a problem. After downloading the latest version of PBI I cannot launch it anymore. Tried to launch with Administrative rights, switched off all antivirus and other protection programs, no change. Seems many users have the same problem. Any suggestions?
