Using Client Parameters to Access System-specific Registry Entries

Assigning local registry values to client parameters provides access to nearly all important system and application configuration information. Any local registry value under the HKEY_LOCAL_MACHINE root may be assigned to parameters of type Alphanumeric, using the following placeholder format:

&HKLM\subkey\name

subkey

Specifies a sub key of HKEY_LOCAL_MACHINE

name

Specifies a registry value name. The current registry value is evaluated when the installation starts. If the value is not available the installation fails.

The value data of a registry value of type DWORD will be transformed into an ASCII string. All other types of registry values will be taken as a string. For example, for multi-string values only the first string is used.

Example:

Assumed any SXP archive file of a package requires the target computer name. Define an alphanumeric parameter, ComputerName, and assign as default value:w

&HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName\ComputerName

During installation of the package, throughout the archive files, the variable $(ComputerName) is replaced with the local computer name.
