SQL Optimizer license management on Citrix server - It just says license is invalid (72997)

We have installed SQL Optimizer on a Citrix server where this application is published for all the users. When we followed regular installation instructions, we are having license issues as by default the license file is saved for single user profile. When I launch the tool, It just says license is invalid, as it trying to load a license file from a user's home directory rather than shared installation.
 

1. Backup “Install.key” in folder "C:\Documents and Settings\All Users\Application Data\Quest Software\Quest SQL Optimizer for DB2 LUW".
2. Move “QSAuthorize49.key” to “C:\Documents and Settings\All Users\Application Data\Quest Software\Quest SQL Optimizer for DB2 LUW” and rename it to “Install.key”
