Error 1606 - HP Computers & Internet

Re: Please Help Unable to Install TIVO Desktop -- Error 1606. Could not access network location %APPDATA%\

The response to "Echo %appadata%" should be
C:\Users\UserName\AppData\Roaming
A space in the user name shouldn't be a problem, but creating a new user may fix the problem because it will create the account with default registry settings which will hopefully have the missing %appdata% information.
If you want to check on this before creating the new user, just for curiosity's sake, check the following Registry key:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders and check the value for AppData in the right hand pane. If it's missing, then that would explain the problem. It should be as listed above, substituting the UserName with the folder name for the user under Users.
Also check the key
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
The value of this key should be
%USERPROFILE%\AppData\Roaming
More keys to check:
HKCU\Volatile Environement (1)
HKU\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders (2)
HKU\Sxxxxx\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders (2)
HKU\Sxxxxx\Volatile Environement (1)
The values in (1) should have the full path spelled out, the values in (2) should use the %USERPROFILE% variable in the path. If the value under HKU\.DEFAULT is missing or bad, then creating a new user probably won't work either. If that value is missing, then I would recommend a clean reinstall of Windows because there is no telling what else is messed up also.

The value for AppData in the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
is C:\Users\Murray Admin\AppData\Roaming
In the key the key
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
The value for AppData is %APPDATA%
The value for Local AppData is %USERPROFILE%\AppData\Local

In HKCU\Volatile Environement (1)
The value for HOMEPATH is \Users\Murray Admin
In HKU\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders (2)
The value for AppData is %USERPROFILE%\AppData\Roaming (all the keys have the %USERPROFILE%\ )
In HKU\Sxxxxx\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders (2)
The value in one of the \Sxxxxx\Software\Microsoft\Windows\CurrentVersion\Explorer\UserShell Folders keys for AppData is
%APPDATA% (Missing the %USERPROFILE%\ ) --- Could this be the problem???
All the other values within do contain %USERPROFILE%\
Do you think editing the key, adding %USERPROFILE%\ would do the trick? If so, it would be alot eaiser then
a re-install. There is not much junk on it as this pc is only about a month and a half old. The other machine
is about six months old. Both are from the same manufacturer (Compaq) but different models.

Also - Using the set command the value returned for %APPDATA% are:
Microsoft Windows [Version 6.0.6001]
