Two new Windows Installer properties are available when you add an MSI DLL custom action to your project to
detect virtual machines:

IS_VM_DETECTED

and

IS_VM_TYPE

. The custom action should be configured to call

the

ISDetectVM

function in the

SetAllUsers.dll

file, which is installed with InstallShield.

In addition, the InstallScript language has been expanded to support the detection. The structure

SYSINFO

contains

a new

bIsVirtualMachine

member, and a new

VIRTUAL_MACHINE_TYPE

constant is available for use with the

InstallScript function

GetSystemInfo

New Support for Setting Permissions for Files, Folders, and Registry Keys

InstallShield offers two new ways to secure files, folders, and registry keys for end users who run your product in a
locked-down environment:

•

Custom InstallShield handling

—In Windows Installer-based projects, you can choose to use custom

support for setting permissions at run time. With this option, InstallShield stores permission information for
your product in the custom

ISLockPermissions

table of the .msi database. InstallShield also adds custom

actions to your project to set the permissions.

•

SetObjectPermissions, an InstallScript Function

—You can use the new

SetObjectPermissions

function in InstallScript events and InstallScript custom actions to set permissions at run time.

With the custom InstallShield handling option, the file, folder, or registry key for which you are setting permissions
must be installed as part of your installation. With the

SetObjectPermissions

function, the file, folder, or registry

key can be installed as part of your installation, or it can be already present on the target system.

Previously, the only option that InstallShield offered for setting permissions was to use the traditional Windows
Installer handling. With this option, the permission information is stored in the

LockPermissions

table of the .msi

database. The new custom InstallShield handling option and the

SetObjectPermissions

function offer several

advantages over the traditional Windows Installer handling:

•

The custom option and the

SetObjectPermissions

function include support for many well-known security

identifiers (SIDs) that are not supported by the traditional Windows Installer handling option.

•

The custom option and the

SetObjectPermissions

function support the use of localized user names for the

supported SIDs, unlike the traditional option. With the traditional option, if you try to use a localized name to
set permissions on a non-English system, the installation may fail.

•

The custom option and the

SetObjectPermissions

function let you specify that you want to deny a user or

group from having the permissions that you are specifying. The traditional handling does not allow you to do
this.

•

The custom option and the

SetObjectPermissions

function let you add permissions to a file, folder, or

registry key that already exists on the target system, without deleting any existing permissions for that object.
With the traditional handling, the existing permissions are deleted.

•

The custom option and the

SetObjectPermissions

function let you configure permissions for a folder (or a

registry key), and indicate whether you want the permissions to be applied to all of the folder’s subfolders and
files (or the registry key’s subkeys). With the traditional handling, if you want to configure permissions for a
subfolder or a file in a folder (or a subkey under a registry key), the parent that is created on the target system
automatically inherits the permissions of its child.
