“Please Install Apple Application Support” – Fixed
I recently united my music collection on a single machine and thus proceeded to clean up on the other PCs and Laptops. Part of my clean up involved uninstalling iTunes on all machines that it wasn’t needed on anymore. While going through the list of installed programms I also noticed something called “Apple Application Support” and thinking it was part of iTunes I hastily uninstalled it as well.
Unfortunately the “Apple Application Support” isn’t only used by iTunes but also by other Apple applications such as Quicktime, so everytime I tried to play a Quicktime .mov I now got an error message prompting me to “Please Install Apple Application Support”.
A quick search on the Apple website netted me no results, it seems this application isn’t available anywhere as download.
After a bit of research on the net, I discovered that the file you need is called AppleApplicationSupport.msi and you can get to it by using either of these obscure ways:
- Open the iTunes or Quicktime installer file with a compression program such as WinRAR and extract the file AppleApplicationSupport.msi
or - Run the install application and leave the program idle at its menus. Navigate to your temporary director and look for a folder named IXPxxx.tmp (xxx is a random number). The MSI program will be located in that folder. Please note: You must leave the installer running. If you close the installer, it will delete the temporary directory.
After you have the file just run it and the errormessage will not bother you anymore.
Happy Quicktiming!

Thank you for your post, it happens the same to me too. I will try to fix it.
