I have MS office 10 CD and product key. I have already installed it on 2 PCs. One laptop died. Bought a new laptop, no CD drive. How do I install MS Office in the new laptop? Additionally, how do I deactivate Office 10 in the laptop that died and re-use it? Thanks.

Check your Office 2010 Licence. Unless it explicitly allows installation on more than one PC, it can only be installed on one PC at a time. You cannot deactivate an existing installation.

If the problem is the lack of a CD drive, beg steal or borrow another PC that has such a drive and copy the disc to flash media or see https://products.office.com/en-us/do...bs%3aprimaryr2

Fyi, external CD/DVD drives are around $20-30.

Except that the OP is using Office 2010, not Office 2016.
