Office 2010

I have just got a new laptop with Windows 8 I have downloaded Office 2010 (as I don't have a CD) but when it loaded It gives me an option to open in verious apps but none of them allows me to install to the OS

What is the filename , including the extension...

I suspect it's an ISO file which needs to be mounted as a drive first..

I'm not 100% sure , but if you right click the file....is there a 'Mount' option?

There is no Mount option, and it just say Type of file: File (in the General Properties list)

Does it give you a choice of opening, run, or save when downloading? Could you post the download page link, please?

I downloaded this and it went in, alright?? But it was an exe file downloader
