TwainExe.exe has stopped working
Try to reinstall your software to your camera, you do it in this way : go to Start--Control Panel--Add and Remove programs. Here you select the Camera software and choose uninstall, after that you reboot the computer and install the software again.
If the problem stil are there, there is to thing you need to do:
1: run chkdsk
2: check if your firewall block your program and your antivirus has quarantine your camera software files.
1: for running CHKDSK, you highlight your drive C: in MY Computer, choose properties and choose the second tab, here you choose "check this drive for errors" check all the possibility and press ok and after reboot the computer and let the program run. After that the computer will reboot by itself and you can try again.
2: open your main screen of you firewall (if your using a specific), see if the firewall gives the permission to the program to run, if not, try to chance the settings to that.
For your antivirus, go to the main screen, here you should bee able to find a feature that is called quarantine, here you can see if there is some files of your program that is here, if it is the the answer, please unblock the files and accept them in the antivirus.
Hope that helps
