Hi Everyone,

Running powerpoint 2010 on windows 7, 64bit. all my office programmes work but the one i need the most for my classroom stuff is not working. it tells me im missing ppcore.dll.

now i have the disks, ive tried putting them in but for some reason they arent working. im getting very annoyed with microsoft right now! when i try to search the internet to solve it im sold a load of programmes at 24+ pounds which is ridiculous as its a microsoft error. microsoft staff have even posted these as fixes on some sites and im not paying for something a.i dont trust and b. might not work.

so can you help please?! this is urgent as i need powerpoint today to sort my lessons out for this week.

thanks in advance
