What permissions do standard users require for Windows Vista?
Standard users need Full Control over the folder which contains the Lighting Technologies program they are trying to access. Identify the program location; for example, C:\LTI, which is the default location for Lumen Micro, Lumen Designer, Simply Lighting and Photopia. Select the folder containing the program, right click for the popup menu, and select Properties. Go to the Security tab and choose the “Users” account. The users permissions will populate a list. Check Full Control and Apply the settings. Close the screen and test under the user account. Note: Photopia users will need to run the PhotopiaReg.exe before running Photopia if it was installed and licensed under a different account.
