Error instaling Power BI desktop

[manubolsonaro]

hi! I'm trying to install Power BI desktop (Windows 7 64 bits) but it shows this error once I try to launch the program. Could you please help? I've tried 64 and 32 bits and it shows the same error.

Thanks in advance

Hi  @manubolsonaro 

1. Is this your first time installing PBI Desktop or updating your version of PBI Desktop?
2. Where did you get the installation package for installation?
You can refer to the installation environment below and download the installation package to reinstall.

Download Power BI Desktop from Official Microsoft Download Center
