I'm sorry this is a rush. John R is right. It should be Tools / Customize / Options / Load from. In this place there is also "save in". If you do your UI (for example, add some toolbars, change them, etc.) then you can highlight the "Save in", enter your name there and hit the "save in". This name will be visible after expanding the list in the "load from" and therefore you will be able to set it . Settings def1024 (800) acstd are standard settings and should not be overwritten. Then you can always go back to them. These files are located in the folder "Config" (.... Documents / DoublaCAD XT Pro 3/Config). They may also find themselves depending on how the installation to be in another place. Best to use the file searching - that have the extension *. xcfg.
