Thanks for that, however this does not work for me.
Firstly my revit.ini file does not have the line pointing to the IES file locations. (see attched file, I had to rename it to a .txt to upload)
The directory C:\Documents and Settings\All Users\Application
Data\Autodesk\Revit Systems\IES does not exist.
(All my paths show Revit Building by the way)
The only reference to IES on my system is under the Accurender\support directory.
Any other ideas? In case it has to do with my installation options see below:
Please note that I am located in Australia and are using Revit 9.0 building series. Upon installation I installed that following content only:
Australian Extentions
APAC
Archvision
Web Library
Accurender
I did NOT install
EMEA (don't even know what it is)
South Asia extensions
Sigapore Extensions
North America imperial
International Metric
New Zealand extensions
English tutorials
All help is sppreciated.
