I have been having an issue running SigmaStudio from my user account (Mark) after I installed it using the admin account (Admin.)
When I start it, it complains about the AddIns.xml file missing, and should it be created. (saying yes or no doesn't work.)
Further, when I try to close SigmaStudio, it complains that it can't find the ToolbarLayout.dat file and any answer won't let me close. I have to end the process from Task Manager.
Doing a little research I found a few files in \Documents and Settings\Admin\Application Data\Analog Devices\SigmaStudio 3.7\
Of course, Mark doesn't have access to Admins files.
I copied that folder from Admin to Mark, (by first logging on as Admin, and copying them to All Users) and Sigma Studio seems to work now.
I will play with it a while longer, and if I find a problem I will get back to you.
