Microsoft's security model in VISTA has caused many people grief and aggravation.  This along with many compatibility issues has forced Microsoft to extend support for XP an additional 5 years.
Report Concierge installs to Vista but you must have administrator privileges and allow writing to the registry.  Detailed installation instructions are available.  Please contact us if you require assistance installing Report Concierge on Vista.

If you are running Windows XP, we still do not recommend updating to VISTA at this point in time.
