How to fix the Windows Error 0x800700c1 Error 0x800700c1

Symptoms of 0x800700c1 - Error 0x800700c1

Windows Errors can be categorized as syntax error, logic error or run-time error.

When a user receives a Syntax Error, the computer just suddenly pop up an error message that something crashed in the background. Programs accessed by the user may stall or completely crash. The user can still use the other applications, but somehow, a confusing message comes up once in a while to say that the accessed program cannot launch because a process is not working.

Run-time errors happen during the time that an application is running. So, when the error occurs, it simply happens without a warning, and the computer gives a notification that there was an error.

Logic errors are programming related. A bug causes unintended output or behavior. Speaking of computer systems which have passed all testing and commercialized, logic error happen only when there had been significant changes in the physical state of the logic board. Perhaps a portion of the actual buses melted together or a similar situation. This can cause the computer to suddenly give off a loud beep or a grinding noise, and may even go to a sudden unstable operation, freezing up or a sudden change in temperature prior to actual crash.
