Error – Office product Couldn’t install
I have installed Office 365 on my system. I preferred to use Office 2010 professional with my Office 365 but when I attempted to install it, an error message appeared “Couldn’t install”. I tried to re-install this product but same error message displayed. Any help would be appreciated.
