Have upgraded to 8.1 from 8 but can not load Archiglazing 1.6
do I have to remove version 8 first! --running Windows 2000
Check whether ArchiGlazing 1.6 works with 8.1. Do NOT
remove 8 until you are sure that it does.
If it does not, contact your reseller for the upgrade.
ArchiCAD since 4.55 ... 1995
