Win 10 lost my Microsoft office Home and student 2007

[Treblis53]

Hi- when I installed win 10 my microsoft office stopped working . I went to list of programmes and it was listed there but it was showing no file size ( should be approx 311mb) . I downloaded it from Microsoft and everything seemed to work and it said it was installed but exactly the same thing i.e no file size showing and no go (I had uninstalled previous ) and tried again but still the same. Any ideas - could it be hardware on my pc ? .

What happens if you right click the Start Button and choose Run and in the Run dialog box you type
winword.exe
hit enter or click OK
