After downloading the AECOsim Building Designer V8i SELECTseries 6 (v08.11.09.829) Readme file from the Fulfillment Center, then extracting it, there is no content on the right hand side of the panel.
When using a different zip method to extract the file other than the default right click, "Extract All" from Windows, the readme file will have no right side content when it is opened. After you download the zip file and select Properties, go to the General tab in the Properties dialog, select "Unblock" and Apply. Then the file will open with all the content. It actually tells you in the Properties dialog for Security reasons "This file came from another computer and might be blocked to help protect this computer".
