Cannot find TTerminal VCL component

Q: I installed the TTerminal component, but when I open the Manager project, the TTerminal is lost and Delphi says that it can't find the TTerminal component? But it is on the Delphi IDE when I start Delphi.

A: Probably MandySoft_VCL.bpl is hidden package for project. Look "Project options/Packages" and check appropriate check box. If it does not help try to find "MandySoft_VCL" text in registry (regedit.exe). Delphi is able to hide package generally.
