Another option is to temporarily disconnect the Linux drive in your BIOS during the upgrade, then reconnect it after.

Have you checked if the Windows partition itself has the full 64GB of free space required for the upgrade? Hope that helps.

Can confirm. Yeah, that's a good point. Also, make sure your Windows drive is set as the primary boot device in your BIOS before starting the upgrade.

This. Agreed, that's a solid approach. Yeah, and just make sure you've backed up anything important on both systems before you start tinkering with the bootloader.

You could also try temporarily disabling the Linux boot entry from within Windows using a tool like EasyBCD, then running the upgrade.

Agreed, that's a solid workaround. Also, make sure your Windows drive itself has plenty of free space, as that's what the installer is really checking.

Same here. Yeah, and before you resize anything, it's a good idea to back up your Linux partition just in case.

Agreed, and one extra tip: temporarily disconnect any non-essential external drives before running the installer again—sometimes it gets confused by those.
