I also had this issue when one day itunes stopped working for me on windows 8...
the error message I received first was: C:Programme files\common files\Apple\Apple Push service.dll is either not designed to run on windows or contains an error.
followed by: ITunes not installed Error 7 (Windows error 193)
Your response addressed how to fix this issue with earlier windows operating systems, but not for windows 8, so what ended up working for me was your advice applied a little differently. For anyone running windows 8 needing to know how to resolve this issue by repairing the Apple Application Support program, try following these simple steps - what a relief it was to have itunes working again after applying b noir's answer to the windows 8 operating system!
1. Swipe in from the right edge of the screen, tap Settings, and then tap Control Panel.
(If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Control Panel.)
2. Click the Programs and Features icon.
3. In the list of programs and features, find the Apple Application Support feature and click to select it.
4.  In the gray title bar above it, click Repair.
5. Approve the window prompts that follow until the repair has been completed.
6. Relaunch iTunes.
Hope this helps & good luck!
