Today 1/29/14 I attempted to update iTunes to the latest version - I got Error 7 (193) on W7 64 bit PC. I did everything to completely uninstall all apple folders on this site. I followed every step. I did this three times.
Apple is slowly loosing me as a valued customer. I attempted to update to the latest version of iTunes (11.1.4.62) for my desktop W7 service pack 1 64 bit PC. It would not upgrade it even told me that the install verson was incorrectly installed. Error 7 (193). Wow. An attempt to update the verson and the whole install is corrupt. I followed every step to uninstall iTunes and all the Apple directories. I installed it only to crash everytime. I repaired it. No improvement. I uninstalled it again as this support sight suggests. Still iTunes began "unresponsive" and closed. I reinstalled on another harddrive - no luck.
How is it Apple with all its glory and money can mess up a simple thing as an update? I, in good faith, do as Apple suggests and now I can't access my purchased content. I will voice my opinion and see if Apple will correct this ASAP for ask for all my money back - well over 40 movies, 2,000 songs and 300 music videos.
