I think I saw that once when i ran a command line project using vtl, and then opened a vtlec project at the same time.
Did you try running the ActivtyController, see if it sees the project open? If so, you could close it from there.
$ man ActivityController # for more info
I'm also getting similar error while execution "vtl show"command.
VTune Performance Analyzer 9.1 for Linux* build 226
Copyright (C) 2000-2009 Intel Corporation. All rights reserved.
The project is already open and cannot be used. Another VTune Performance Environment session has opened it.
Can you please give any suggessions for this ?
Iguess that other user is using this tool with same user account, or VTune Analyzer has exited but some components are still alive (remained) in the system.
You may use "ps -ae" to check if some VTune Analyzer related processes in the list, so you can kill them first then use vtl.
