Allow other users when upgrading from version 8 to 9

I got my iMac about 10 months ago and installed Parallels to run my Win 7 programs. Originally I just allowed myself to access Parallels. Now I want to upgrade to version 9 and want to allow another user on my computer to have access to my Win 7 programs. Will I have the option in the Parallels 9 upgrade process to do this. If not, how can I allow access to Parallels by myself and another user on this computer.
