Crashes upon program startup

1.  System.Core Crash

If you get a message similar to this when CBoxRun starts:

An error occurred creating the form. See Exception.InnerException for details. 
The error is: Could not load file or assembly 'System.Core, Version=3.5.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

Make sure that you have .NET 3.5 SP1 or later loaded.  To determine which version of .NET is installed on your machine, check your Uninstall list, or  look in your Registry as shown here:

http://msdn.microsoft.com/en-us/kb/kbarticle.aspx?id=318785

If needed, you can download the .NET runtime and service pack from the Microsoft Web site.

2. MainForm crash – line 130

If you get a message similar to this:

Object reference not set to an instance of an object.
at CBoxRun.MainForm.MainFormNew_Load(Object sender, EventArgs e)
in B:\9soft\Projects\CBoxRun\CBoxRun\MainForm.vb:line 130

Your WikiEntryList.xml file may be corrupted or read-only.  Make sure that this file is not read-only and that it can be edited by the current user (by opening it in Notepad and saving it with no changes).  If the file is editable, try downloading another copy of CBoxRun and replacing the WikiEntryList.xml file in your CBoxRun directory with the one from the new .ZIP file.

Security Error on Windows 7 / Windows Vista

If you’re installing to the Program Files directory on Vista or Windows 7, you may get a security error unless you run CBoxRun as an administrator.  This is because CBoxRun writes some data files to its install directory – which is necessary when running in portable mode – and Vista/Win7 doesn’t normally allow users to write to this directory.

    Hello,

    When trying to start CboxRun, it crashes with the following error:

    Program Message:
    The following unhandled exception was caught during CBoxRunexecution. The application cannot continue.

    Stack Trace:
    Object reference not set to an instance of an object.

    Anything I can do to fix this?

    Thanks!

      I’ll take a look. Does this happen the first time that you try to start the program (i.e. before you create any game definitions)? if not, can you give me a little more detail?

    Yes, I could never get into the program itself.
    I started for the first time, entered the dosbox locations, and then the error appeared before I could get into the program.

      IT looks as if the WikiEntryList.xml file may be missing or damaged. Try downloading another copy of CBoxRun, open its Zip file, and drag the file WikiEntryList.xml into your program directory. If the WikiEntryList.xml file is already in the directory, make sure that it’s not read-only and that you have access to write to the file (i.e. try opening it in Notepad and saving it).

    Hello!
    This FAQ answered my question! It worked. It wasn’t read-only but the zip had been copied from another computer so it may have been altered. Thank you, Cboxrun is a good product (the greatest frontend i tried many), I hope you won’t lose faith 🙂

    • January 4, 2011 at 5:12 pm

      I’m glad you got it working! Thanks for your support.

    Yup, it worked!
    Thanks man, it’s a great program.

    • January 15, 2011 at 11:10 pm

      Glad it worked!

      Since this file is auto-generated anyway, in 0.51 the program will rebuild it automatically (if possible) rather than throwing an error, and we’ll add a more descriptive message if an error does occur.

    Is there a way to arrange the boxart view? In detail view, the programs are lined up alphabetically. In Boxart, it’s arranged by which one is added firs, and can be frustrating.

    • March 6, 2011 at 9:21 pm

      I’ll add that to the requested features list. I’m surprised that it doesn’t use the sort order that is selected in details view – that’s what was intended. Thanks for the feedback.

    Hi,

    I’ve been using this frontend for a couple days and, feature-wise, it is my favorite. It does, however, crash on me a lot.

    Whenever I try to “Edit DOSBox Default Config File” or “Edit Default keyboard mapping” I get the following error message.

    I’m on Windows 7 64-Bit. I’m running CBoxRun.exe as an administrator but I’m still getting the errors. Also, every time I run the application, WikiEntryList.xml is deleted somehow (even single time). The games themselves run fine (at least a dozen that I’ve tried) but I figured you’d like to know about any errors. I also just installed .NET Framework 4 from here:

    http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9cfb2d51-5ff4-4491-b0e5-b386f32c0992

    but I still have the same crashes. Thanks for any help.

    Program Message:
    The following unhandled exception was caught during CBoxRun execution. The application cannot continue.

    Stack Trace:
    Index was outside the bounds of the array.

      Thanks, I’ll look into it.

    I’ve been having the same problem. When I install the program, the WikiEntry xml file is there – but as soon as the program starts, the file seems to delete itself.

    Starting the program while connected to the internet seems to go fine – but it won’t load when I’m not connected to the internet, throwing up an error that the WikiEntry xml can’t be written to.

    I’ve tried replacing and changing the security of the file: didn’t work. It still won’t load unless connected to the internet, and if I am the file disappears wen the program starts.

    • April 25, 2011 at 7:31 pm

      Thanks Matt. I’ll fix this in the next release.

    Thank you! Yours is definitely my favourite dosbox frontend, but unfortunately I don’t have 100% internet accessibility so it’s annoying I can’t use it!

    Hi, i just downloaded this so i can play Master of Orion, but i have no idea how to set this up. I tried to chose the Master of Orion icon, the one i always used to click, but it wouldn’t appear, so i had to chose the other ones (Install, Orion, etc), but when i start DosBox the only text that appears is:

    Z:\>MOUNT C “C:\Games”

    Drive C is mounted as local directory C:\Games

    Z:\>C:

    C:\>

    The reason i wanted to use this, its because for some reason, i can’t play MoO anymore, i think i messed up the config file, and now it says I need at least 1024kb of expanded memory to play.

    Please help me.
