Windows file list

The following files and directories should NOT be copied from one computer to another:

KeyAccess Audit, which is located in one of these directories depending on OS version and KeyAccess version:
C:\ProgramData\KeyAccess\
C:\Documents and Settings\All Users\Application Data\KeyAccess\
C:\Documents and Settings\All Users\Application Data\
C:\ProgramData\
C:\WINDOWS\
C:\WINNT\
KeyAccess Offline, which is located in one of these directories depending on OS version and KeyAccess version:
C:\ProgramData\KeyAccess\
C:\Documents and Settings\All Users\Application Data\KeyAccess\
[User Profile Dir]\Local Settings\Application Data\
C:\WINDOWS\
C:\WINNT\
portable.dir, which is a directory and is located in one of these directories depending on OS version and KeyAccess version:
C:\ProgramData\KeyAccess\
C:\Documents and Settings\All Users\Application Data\KeyAccess\
[User Profile Dir]\Local Settings\Application Data\
C:\WINDOWS\
C:\WINNT\
[Any Drive]:\portable.dir\

The following registry settings should NOT be copied from one computer to another:

registry: HKEY_CURRENT_USER\SOFTWARE\Sassafras\KeyAccess\Settings\pref
registry: HKEY_CURRENT_USER\SOFTWARE\Sassafras\KeyAccess\Settings\settings
registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\KeyAccess\Settings\pref
registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\KeyAccess\Settings\settings

Note: The KeyAccess client install creates a keyacc.ini file in the windows directory even when you accept the default, “store settings in registry”. The line, “registry=2” in keyacc.ini tells KeyAccess to consult the registry for additional settings, so keyacc.ini must be included in the cloned image. If you have customized the client install (using the k2clientconfig utility) so it stores all settings in the keyacc.ini, then this file must be edited before cloning. Remove all lines beginning “previd” or “prevhw”.
