When trying to load an HET program in HET IDE, I had an error about a SynaptiCAD thant spanned a few message boxes. It looked like some command line flags that gave me no clues of any kind. It also crashed HET IDE. Rebooting did not solve.
I have uninstalled SynaptiCAD and reinstalled it in its the default directory. First time I had it install somewhere clean (Program Files) instead of c:\SynaptiCAD. It has solved the problem.
IF HET IDE uses an hardcoded location for SynaptiCAD, that is VERY VERY BAD coding. Otherwise, something else is wrong.
