You cannot install Power BI using a personal email account, as Power BI requires a work or school email account for sign-up. If you do not have a work or school account, you can still try out Power BI by signing up for a trial of Microsoft 365. During this process, you will create an "onmicrosoft" email work account, which you can then use to access Power BI. Keep in mind that a credit card is required for the Microsoft 365 trial, and you should cancel it before the trial ends if you do not wish to be charged.
