Installation

Administrative privileges are required to install the software.

Simply execute the SafeGuard PrivateCrypto MSI package to install the software.

If the Microsoft Windows Installer component is not available on the computer (e.g. on Windows NT 4.0), there is a larger EXE package for SafeGuard PrivateCrypto that installs the Windows Installer component first automatically.

It is possible to install the software on a network location. Note that in this case some files might be left over in the installation directory after uninstallation.

The software can be used immediately after installation. Normally, no reboot is necessary after installing SafeGuard PrivateCrypto. Under Windows NT 4.0, however, updating some older Microsoft redistributable components might make a reboot necessary.

When installing the software with Active Directory (GPO), the following issues should be considered:
•	SafeGuard PrivateCrypto can only be installed per computer (Computer Configuration), not for single users (User Configuration).
•	If a program package has a different language than the operating system of the client machine, then the setting “Ignore language when deploying this package” must be enabled for the package, otherwise the software will not be installed automatically.

Known Issues
•	The SafeGuard PrivateCrypto shell extension cannot be used by 64-bit Windows Explorer.
