You should just be able to choose the 64bit version from the download page.

uninstall 32bit office version and install the 64bit instead.

Hi,

I have windows 7( 64 bit operating system). I was using MS Office 2013. The excel in that was 32 bit without PowerPivot, moreover it was unable to manage large data sets and frequently there was memory issues. Therefore I purchased a standalone version of excel 2013. During purchase I was told by sales rep that a 64 bit would be downloaded as I was having 64 bit operating system. But to my surprise I got 32 bit excel and I am facing the memory issue again.

Can someone help me to upgrade my 32 bit standalone excel to 64 bit?

Thanks for your help in advance!

Hi,

Please use the Product key and download the 64bit Excel from this site:https://products.office.com/en-us/download-back-up-restore-microsoft-office-products?legRedir=true&CorrelationId=49472402-7d4c-476a-b7e1-7ed6b428a093

Note: Please uninstall 32bit Excel in your pc and then choose 64bit version before download.
