Yes; however, Instant Protection PLUS 3 requires the license file and aliases to be opened from a program that has Administrator privileges the first time they are opened. In Windows Vista and higher, they must be opened with elevated Administrator privileges as described in our Using Instant Protection PLUS 3 on Windows Vista and later whitepaper. If this is not done, you will receive an "Error 42".
After being opened with Administrator privileges, Instant Protection PLUS 3 will set the necessary permissions so that even a standard user will have read/write access to your license files.
The /OPENLF command line parameter is available to assist in creating and setting permissions for the license file and alias files. Refer to the Instant Protection PLUS 3 Wrapper or Instant Protection PLUS 3 DLL deployment topics for more information on how to address this.
