Hello everybody!
As I have learned a lot from this community I want to share a solution to a problem I had: The Simplify3D software did not start.
It use to work just fine, but after an update of my graphic-drivers the simplify3d program did work anymore.
Even after uninstalling, redownloading and reinstalling it didnt work. while other programs did not seem to suffer from the new drivers...
It turns out that after uninstalling there is still a "software key" left.. ( what ever that may be)
But after running CCleaner I removed it.
Then you can reinstall the simlify3D software again, etvoila! it works again!
I hope this is usefull to somebody out there....
