CrashDoctor is a software utility designed to prevent programs from crashing or to recover them in case it happens by working as a JIT Windows debugger.CrashDoctor has another useful feature, once a program crashes, CrashDoctor monitors the execution of the program. If the program tries to open an existing file for writing CrashDoctor intercepts this and copies the original file to a backup location. This prevents any further damage done by the misbehaving program. The current version of CrashDoctor however doesn't prevent this if program already has these files open.CrashDoctor also works like a debugger chooser. After installing CrashDoctor if a program crashes, the CrashDoctor recovery screen shows up. This screen lists debuggers available on the system and you can select a debugger to debug the crashing program instead of recovering its crash. Note here that once you start debugging the program, you won't be able to recover it.Features Runs as JIT debugger so no overhead when no program is crashing Extremely light-weight and doesn't slow down the process even when recovering it from the crash Once a process crashes, CrashDoctor intercepts if the process tries to open a file for write and makes a backup copy of the file to prevent data loss Works as a debugger chooser also if you have multiple debuggers in your system. Upon a program crash, you can chose which debugger to use to debug the program (in case you don't want to recover the process from crashing). Comes with an easy to use graphical user interface.
