Make 32 bit default application over 64 bit on the same PC

Hello there.

I have both Power BI Desktop - 64 and 32 bit on the same PC.

64 bit version was the first one to be installed and just yesterday installed the 32 bit version too

32 bit installed in C:\Program Files (x86)\

64 bit installed in C:\Program Files\

However, I am unable to change the default application for pbix files to the 64 bit version after the 32 bit version was installed. I have tried "Open with" and pointed to the .exe file to where the 64 bit version is installed. However, the application still opens in 32 bit by default. Is there any suggestions on how I can change the default application to 64 bit version instead of the 32 bit version please. Thank you.
