You will need to set appdata as a system variable.
In the environment variable section, set the following system variable:
Name: appdata
Variable: c:\users\username\appdata
Where username is replaced with your name.

And now a non-technical response from a non-technical guy. I had this problem, and it seemed to originate when I renamed by administrator account (in Windows Vista) and added some additional new (non-admin) accounts.
None of the fixes listed on here helped me, and the registry all seemed to be correct, but I still could not install any new software.
The fix? ... Creating a new administrator account. Not only could I now install from the new admin account, but it somehow jogged all of the other accounts into working properly again too.
I was experiencing the same problem as everyone else here, applied the MS hotfix and used the Fix it tool+manual inspection and correction. I finally solved the problem by right clicking computer, properties, advanced settings, environment variables, and adding this entry to both system and user variables,
name:APPDATA value:%USERPROFILE%\AppData\Roaming
DethKore ~ thank you so very much for your post!! Adding the APPDATA as you described to my user and system variables tables has resolved my problem!!
DethKore,
Great! It worked for me, finally!
(I tried adding registry etc but it didn't for some reason, it only worked only after adding environment variable)
Thank you DethKore. It worked perfectly. I had spent hours trying to resolved it before I came across your solution. Thanks so much.

YOU ARE A GOD, SIR (MA'AM?)
I SIMPLY CANNOT THANK YOU ENOUGH. I WASTED FOUR HOURS ON THIS "APPDATA" PROBLEM WITH iTUNES.
THANK YOU, THANK YOU, THANK YOU.
After trying suggestions made by two software manufacturers, which failed to load, I Google the 1606 error and found this site. Thanks to the simple old school technique posted by DethKore-- it worked for both instances mentioned above. I, OS1938 was saved many hours as a novice in this great marvel I've been using since the mid sixties, computers. Windows Vista is my OS. And I like to renew the question, 'Does anyone know what suddenly causes updates and new loading of software to fail.' Yes! I was thinking of buying a new printer, but fortunately, software updates started to occur. At age 73 you have help me to continue learning something new. Thanks for this forum....
Nihir, thank you so much. I have been trying to figure this out for over a year. Creating a new user account WORKED! Thanks so much!
