PBI RS October 2020

Hi to everybody, 

For professional reasons, I must use Power BI Report Server Desktop in the October 2020 version. I had to change my computer and I have lost the .exe for this version. I am unable to find it in any repository. Could someone tell me where you can find this version or the May 2020 version so that I can further develop my work.

Thanks in advance.

Regards,
