[Error 1606]

I'd the same problem with Vista Ultimate and AutoCAD 2008, SEVERAL problems.

 

I've fixed this with adding the next registry entries (Copy & Paste to a txt file, replace the "@USERNAME@>>" string to your actual Windows account name, rename it to name.reg, and import into the Windows Registry):

 

Windows Registry Editor Version 5.00

 

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]

"!Do not use this registry key"="Use the SHGetFolderPath or SHGetKnownFolderPath function instead"

"Local AppData"="C:\\Users\\@USERNAME@\\AppData\\Local"

"My Video"="C:\\Users\\@USERNAME@\\Videos"

"AppData"="C:\\Users\\@USERNAME@\\AppData\\Roaming"

"My Pictures"="C:\\Users\\@USERNAME@\\Pictures"

"Desktop"="C:\\Users\\@USERNAME@\\Desktop"

"History"="C:\\Users\\@USERNAME@\\AppData\\Local\\Microsoft\\Windows\\History"

"NetHood"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Network Shortcuts"

"Cookies"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Cookies"

"Favorites"="C:\\Users\\@USERNAME@\\Favorites"

"SendTo"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\SendTo"

"Start Menu"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu"

"My Music"="C:\\Users\\@USERNAME@\\Music"

"Programs"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs"

"Recent"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Recent"

"CD Burning"="C:\\Users\\@USERNAME@\\AppData\\Local\\Microsoft\\Windows\\Burn\\Burn"

"PrintHood"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Printer Shortcuts"

"Startup"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup"

"Administrative Tools"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Administrative Tools"

"Personal"="C:\\Users\\@USERNAME@\\Documents"

"Cache"="C:\\Users\\@USERNAME@\\AppData\\Local\\Microsoft\\Windows\\Temporary Internet Files"

"Templates"="C:\\Users\\@USERNAME@\\AppData\\Roaming\\Microsoft\\Windows\\Templates"

Good Luck!
