1 Fix: iTunes UN-inst / Inst Issues

Question

http://support.apple.com/kb/TS5376?viewlocale=en_US
The above covers multi-issues BUT certainly the Apple Mobile Device Sppt --- Uninstall problem.
See #2 in above link and Expand the [32-64 and 64-Bit System] links to see WHAT to Manually UNinstall in (64 bit) Program Files (x86) and              (32-64) Program Files.
The Apple Sppt staffer who had remote access to my friend's computer dealt with the Program Files (x86) only BUT I'd look at them all per the instructions.
iTunes and Apple Software Update were already Deleted.
He skipped the Apple Mob Dev Sppt problem and uninstalled Bojour.
He then went to Program Files (x86) per the above links and did a manual Delete in Comon Files\Apple, although there are multi-deletes to do per the instructions.
He stated the Manual Delete(s) was Key to most people's problems.
After the Manual Delete we RE-BOOTED, downloaded iTunes, and did the Install with 1 Glitch as follows: a pop-up stated the Registry Settings to Import and Burn Cds was missing and that could be from having another Burner App installed....REinstall iTunes.
We didn't because that's not anything our friend does, and I presume her iPhone update capabilities are there.
Logged into Store but that's all.
Try manual Delete(s) as described before Installing iTunes again.
I'll update the CD Burn/Registry isue when I can reach Sppt again.

Answer 1

EDIT: 2/16/14: I was told that the Pop-up about Missing Registry Entries to Import / Burn CDs can be corrected by (1) Starting Over and (2) Uninstalling the List in #2 as directed ref support.apple.com LINK just below, PLUS UNINSTALL QUICKTIME, too.
The C:\Quicktime Files should be checked for complete Deletetion by Uninstall, and manually Delete any left-overs.

We didn't because that's not anything our friend does, and she Sync'd her iPhone and logged into the Store.
Try manual Delete(s) as described (incl Quicktime (See Edit at Top) before Installing iTunes again.
