  1. System.IO.FileNotFoundException


    So, I'm trying to run this aplication that needs to write stuff to the hosts file and it seems like the aplication can't find or access this file however all of my permissions seem to be set up correctly to access this file.

    Log:

    See the end of this message for details on invoking
    just-in-time (JIT) debugging instead of this dialog box.

    ** JIT Debugging **
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
    <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

    Any help is appreciated.

    :)

    In post 26 there were steps listed to fix the operating system corruption.
    Are you able to follow them?
    In post 29 was the suggested dism repair command.

  4. System.IO.FileNotFoundException

    PC Build Steps

    Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval
    • Install system in case
      • Remember to connect SSD and optical to same SATA ports on motherboard
    • Turn on PC
    • setup HDD
    • run blend test in prime95 for 30-60 min
      • run realtemp at the same time
    • While in Prime95 test
      • if CPU goes above 70c in RealTemp, I have a leaky CPU
      • if my system locks up or blue screens, there is an instability in the system somewhere
      • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!
    What do you guys think??
