If you have a SR0 CD version of AccuRender, try copying the file Setup AccuRender.exe (very large, over 460MB) from the AccuRender folder on the CD to your local hard disk (such as to your Desktop), or to a shared drive on your network. Then launch that file from your station and the installation should complete successfully. Once AccuRender, is installed, you can delete the Setup AccuRender.exe file, it is not needed for running AccuRender.
If you still have problems installing AccuRender, please contact tech@mcneel.com for more information.
