When I try to menuload a .cuix on a machine that has UAC set to high, The menu group comes in, but the toolbars associated with it do not. I know this sounds like AutoCAD support but it is .net related as the .cuix is loaded through .net. The pull down appears OK.
If I manually set UAC to it's lowest setting then they come in, is there a reason for this?
Found out why,
The cuix is copied from the Programmes folder to The appdata folder for each new user that logs into the PC. AutoCAD was unsing the first .cui it came accross witch was in the Programmes folder. On the vast majority of clients write access is denied here. So I adjusted the code to only read the one from the appdata folder.
