Gearwizard doesn't work.

[VW181]

Hello,
I have downloaded the gearwizard from the Siemens site.
I downloaded the NX version gearwizard_nx.zip but it's an old one, from 2002-11-14.

Installing went well, i have the toolbar now, but when i click a button (doesn't matter which one) i get the error:

Failes to load image - see log file for details
File name: C:\Gearwizard\application\tw.dll
Function name: ufusr

Only the dll file is different for every button.
And at the location C:\Gearwizard\application are all dll files


The text in the logfile is:

###########################################################################

Does anybody has a solution or is this NXopen program to old to use in NX8?

Ore is there a better way to create a gear?
(I find it very strange that gears are not an standard option in NX )

Hope someone can help us.

Thanks in advance,
Tjeerd
