The step mentioned above works most of the times but sometimes it does not. The Archetra ArchestrA IDE will issue the following error message.

Check in failed for object “XXXXXXXXXXX”.
Error: Object is checked out by another user.

At this point you would have to walk over to your buddy and tell hime to check in the instance so that you can work on it.
But if he/she has already checked in and it is showing as checked out, then you can use another method to force check in of the instance.
Right-click on the instance and then select “Override Check Out” fom the context menu.
