Installation problems with various software (Windows Vista)

by APGamerZ / May 12, 2009 9:21 AM PDT

When trying to install a program I am greeted with a message: "Internal Error: failed to expand shell folder constant userappdata".

I am not on an admin account but since it requires to be run as administrator, this is not an issue. A similar error occurs when I try to install another application "Error 1606: Could not access network location %APP DATA%".

It's apparent that both problems have to do with my AppData folder. However, all permissions are set properly. The folder is in its proper place and everything appears fine. I have cleared temporary files from IE, but the problem still persists. I have deleted the User Shell key in the registry and restarted, but still the problem persists.

I am frustrated and just want to find a way to fix this problem. Oddly when I searched the internet for a solution many people have been having the same exact problem. The even stranger part is that I have only found entries of this problem within the last two weeks. I don't know if this is a virus pandemic or something less sinister. All I want is a definitive answer on how to fix this issue. Every response I have seen thus far has done nothing to alleviate the problem. Read this entire message carefully and then come up with a response.

Thank you.

Thank You.

I just realized my error was deleting the Key on my User account rather than the Admin account's key. Thanks for the help because I would never have fixed the problem without it. By simply revisiting the solution I thought I had already tried I was able to fix it.

Deleting the key in the admin account worked perfectly. Thanks a million.

What is "deleting the key"?

I have this same problem and would like to fix it as well but I don't understand what you mean by saying you "deleted the key."
