I've copied off the c:\vbai\products\ folder and its subfolders, plus the folder that contains my VI's used in "Run labview" steps. Is there anything else I have to do?
To restore then you would just copy those files back on and reboot?
If you're using the Product Selection feature, you also need to backup C:\VBAI\Vision Builder.ini. The Vision Builder AI ini file contains Product Selection information.
