I have a home build desktop PC and I recently backed up all my files and folders with the intention of upgrading to Windows 10. At present I cannot do this, but what is more frustrating is that I cannot download any software or programs, even adobe acrobat reader will not install ! , I figured that I should have The Service pack for Windows 7, but like the aforementioned, it Will download, but when I open it to install it will not and this is the case for any software. Can anyone help with advice ?
