Fixing the Msvcr80 bug ?

Question

Along with hundreds (?) of other users, I too met a huge problem when I innocently allowed Apple to update my iTunes with the latest version (11.1.4).  But checking the Apple discussion forums, I found a recommendation by TuringtestII FIXED THE BUG COMPLETELY, per the procedure below:
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
o                                               iTunes
o                                               Apple Software Update
o                                               Apple Mobile Device Support (if this won't uninstall move on to the next item)
o                                               Bonjour
o                                               Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
APPLE itself was completely unhelpful, but am indebted to TT2 for their excellent fix.  Time consuming, but worth the hassle once it's all done.

Answer 1

I have to make an explanatory note:
on my MAC the problem with screensharing occurs when scaling (Sreensharing / Preferences / Viewing) is off. So where is no need to delete the above mentioned file but to set scaling to "on".
