Me too it seems a problem with the installer
Unfortunately, I think that are more problems with the installer: after I copied dclcxSchedulerD11.bpl into system32 folder, the error didn’t occur anymore, but, after a while, I got a similar error about dxRibbon. This time the error didn’t go away if I reopen the project and I had to recreate the project from the beginning. It’s weird because I had problems only with DevExpress + dbGo
Also, I got a annoying flicking when I scroll a dxGrid
After I manually compiled the components all the errors disappears, including flicking.
