Windows 10, 64bit.
After installing HET IDE, installed SynaptiCAD to default location as installer wanted on C drive; different to HET. On startup, HET IDE doesnt start as it's missing many SynaptiCAD dlls, all which are in its installed folder.
Also, cannot register those dlls as they not registerable with windows regsvr32.
Solution I got to work is to start HET IDE from within the SynaptiCAD folder. E.g., in the shortcut for HET IDE I edied the Start In:
Now it starts fine.
