AWinstall supports the Variables syntax for easy access to the System Registry and Environment variables.
To get a System Registry key, use the following syntax: ${REG:RegistryPath}. For example, ${REG:HKLM\SOFTWARE\Microsoft\Internet Explorer\Version} returns the version of Internet Explorer installed on the target machine.
The following predefined registry roots are available:
Root string |
Value |
HKLM |
HKEY_LOCAL_MACHINE |
HKCU |
HKEY_CURRENT_USER |
HKCR |
HKEY_CLASSES_ROOT |
HKCC |
HKEY_CURRENT_CONFIG |
To read an Environment variable, use the following syntax: ${ENV:VariableName}. For example, ${ENV:NUMBER_OF_PROCESSORS} returns the number of processors installed in the target system.
You can use the Pseudo-Variables either in your scripts (for example, in the Installer.Variables method) or directly in your tasks and actions:
