Hi,
I installed HDL Desiner 2006 on Suse 9.0 and it worked correctly, but when I installed it on openSuse(10.2), it says "Error:Could not create fontset for font -adobe-helvetica- ...". It seems that the font part of new suse versions had been changed.
Actually adobe helvetica is a commercial font usualy distributed with adobe's acrobat reader, try installing adobe's reader 7, and if it's not there, try and use adobe's reader 5 from suse 9
