I'm brand new to creating unattended installs but wondered if someone could point me in the right direction. I want to install O&O Defrag 6 which goes on OK but I cannot register automatically. Looking at the previous example on http://unattended.msfn.org/xp/applications/oodefragpro.htm it looks like I should be able to create a reg file with the following :- [HKEY_LOCAL_MACHINE\SOFTWARE\O&O\O&O Defrag\6.0\Pro] "User"="InsertName" "Company"="InsertCompanyName" "SerialNo"="InsertSerial" Trouble is, if I create something like this and double click the reg file it says "Cannot import - the specified file is not a registry script. You can only import binary reg files from within the registry editor. Any ideas anyone. Cheers Steve
