Installing LPSolve IDE (presente and beta versions from Sourceforge) leads to impossibility of using the programa as it complains "Cannot create file "C:\Program Files (x86)\LPSolveIDE\_tmpfile." Access denied.
Even quitting is impossible as the message changes de file to "default.lpo"❕❕
Only way of exiting the IDE is via the Task Manager...
