You can install the files manually. Either use the .pas files or .dpk files.
I have installed that component successfully using the "VirtualTreesReg.pas" which is located after installing the component intall exe file under:
C:\Documents and Settings\All Users\Documents\Soft Gems\Virtual Treeview\Design
(it might differ at your machine)

Go to File -> New -> Package - Delphi. In the right side of the Delphi IDE you will find "project group" right click on "contains" and select "Add" then locate the file "VirtualTreesReg.pas" then OK. Right click on "packagex.bpl" and select "install" the component will be installed and located under "Virtual Controls" in the "Tool palette".

Search for "DesignIntf.dcu" or "DesignIntf.pas" (also expect to be asked for others) just look for them and add them to the component's folder path that you added to the library path.

Error occurs when installing components built for Delphi 5 or before!!!

There's already an EE question dealing with that issue...
