Install 64 bit version of Office 2019 Home And Business

Dear RajivDaga,
I'm Renzo, I'll help you with your question.
You could try with following process:

The 64-bit version of Office is automatically installed unless you explicitly select the 32-bit version before beginning the installation process.

To install either the 32 or 64-bit version of Microsoft 365 or Office 2019, follow the steps in Install Office on a PC.

Thank you "rdazarola" I went through this support document and have tried following the steps but I do not see the option to download 64 bit, I am not making any manual change in the download I am just clicking download and post-installation when I checked it was 32 bit. For my office laptop, I can choose 32 bit / 64 bit from download but did not see this option for my personal option. Any suggestion as to where can I download the same?

When I sign in to my account and enter the details I just see a download option but the option to choose 32/64 bit is not present.

The moment I click on download it downloads a file which when run then starts the install which downloads and install the application. But post-installation when I check it is 32 bit. Hope this helps
