Environment variables are only evaluated during the software depot runtime and do not change the environment of the Windows system. When used, they are enclosed between two percent characters, e.g., %WindowsUser%.
Environment variables allow you to make the software depot independent of the location where the document is actually stored.
In addition to the environment variables, there is a variety of predefined internal variables which can also be accessed via a % symbol. The following table provides an overview of these variables. Neither the internal variables nor the defined variables are case-sensitive. The internal variables are checked first, followed by the environment variables.
The variables from PackageID to Check vary from package to package and always refer to the current package. Table environment variables
