PeopleTools 8.51 Cient on Citrix 4.5

Does anyone have any experience installing PT 8.51 client on Citrix?  It works fine for me since I installed it but not for anyone else.  The problem: Previous PT version put registry entries under HKEY_LOCAL_MACHINE but 8.51 uses HKEY_CURRENT_USER.  I tried the Citrix "Install Mode" which is supposed to work by shadowing the registry entries and then copying them to the appropriate location under HKEY_CURRENT_USER when necessary, but that is not working.  I suppose we could load the registry another way but would like to know other's experiences.  Thank you.
