I deleted Apple Application Support :'(

I'm posting here because this topic appears on Google when you ask this question, sorry gentlemen moderators...

How I solved the problem with the initial pointer mentioned above

- Start - Search - Apple software update
- Reinstall "apple software update" for those who might have deleted it as well
- Search for updates with "apple software update" you won't find the support application
- Here’s the little trick, you need to reinstall iTunes and magic of all magic... QuickTime works again...

I hope this helps those who are struggling to find a solution since the forums are lacking explanations on this topic

Good luck

thank you a thousand times, it finally works (thanks to the iTunes installation)

look at your programs, type apple software update and click on it, it will offer you to install a new item, click on ok and it will download automatically.

Hello everyone, I have the same issue (which I won't reveal unless I get annoyed once again) but here I am with the same error message as you, and I've done exactly as I was told, that is to re-download iTunes and install it and... oh! Still this damn error message, it drives me crazy
Does anyone have another solution, please?
Please note that my computer in question is not connected to the Internet
Thanks in advance

Yes, but I have Windows 8 and I don't want to uninstall iTunes because all my music will be erased. What should I do?!
