Hi Gabriel,
Not good! However, let´s dig in and see what´s wrong.
Thanks for the pictures. That problem must be fixed.
Another user have just now also crash problems for some reason. Netcam studio crashing
Some questions:
1.Was it a Windows update just before this happened?
2.Did the computer shut down due to a power failure or was it a restart or something that ended NCS in a non controlled way?
3.When you do a fresh install after such a crash you must remove all files. First, use the installation program and do a Remove. Then there are several configuration files that also must be removed. These files are probably causing this crash. Go to C:\ProgramData\Moonware\Netcam Studio and remove what´s in there. If you have the Library with files there that you want to keep, do a backup of these files. Then go to C:\Program Files\Netcam Studio - 64-bit and delete what´s left.
4.Now you can start the installation process again.
It is also interesting to see why it crashes so go thorugh the link Netcam studio crashing The important part here is the Event Viewer. If you can find the Error when NCS is starting, please make a picture of that and post it here or if you find something else of interest 
Good luck,
Henrik
