Kathleen, I have tried to install FRx 6.78 on a Windows 64 bit desktop with a network shared Sysdata folder and have not been sucessfull to date. What I have been able to do is to install locally on a Windows 64 bit with the Sysdata folder local as well. To do this here are the steps I used. Install Version 6.78, C:\FRx. Install Service Pack 9. Install Hot fix for 9. Install Service Pack 11. When I run the installers I run the executable as Administrator, right click on the executable and in Windows 7 you have a option to run the program as Administrator. This method works if it is a one user otherwise you may not be able to.
