Unable to open excel files

[ipbr21054]

Now & then i am unable to open an excel file.
The majority of my files are extension type .xlsm

I have them on my taskbar but clicking them does nothing.
I have them on my desktop but even right clicking them & selecting open also does nothing.

Ive look at the assigned app that opens then & excel is selected.

Any issues that you are aware of as im having to switch off pc then restart it for them to then open again

With the office i have installed i had to download it.
I was thinking of maybe a repair ?

But i have no disc to pop in my pc.

Can you advise from that as if i can do it & will it overwrite all my current settings that i have setup within the software ?
