R zoo installation

Hi

I am running into a problem installing zoo on my PC (HP 98000 PC running Windows Vista).

The error message is a 'permissions' one claiming I don't have permission to write to a subdirectory ... c:\Program Files\...etc

But I am the administrator with full rights, so I dont see why this would happen.


Has anyone seen this and know of a cure?

Thanks in Advance

NB Ist time around, the zoo installation asked me if I wanted to create a library in my local directory, to which I replied yes. Since then (on 2nd / 3rd 4th attempts after re-boot to be sure)  it has never asked that question again. Which makes me suspect a generic installation issue rather that pure Windows permissions issue.
