Something went wrong! Cannot open Power BI Report Server May 2021

[Anonymous]

I installed Power BI Report Server (the latest version May 2022) but then realised that my company's server is using ver May 2021. Thus, I have no choice => uninstall ver May 2022 and install ver May 2021. However, after downgrading, I can no longer open Power BI Report Server on my laptop. The below message appears. I have tried to uninstall and reinstall it so many times but still cannot. This error only disappear if I reinstall the latest version (i.e. May 2022). However, this will not help as I can only use ver May 2021. Is there any solution for this issue, please?

Hi @Anonymous ,

Test to uninstall your desktop again, but this time please delete content in the following path: C:\Users\yourusername\AppData\Local\Microsoft\Power BI Desktop
Then, reinstall this application with "Run as administrator"

Did I answer your question? Mark my post as a solution!
