This page contains a collection of reported problems that prevent RoboBridge from working normally.

1 Possible causes for not being able to install RoboBridge:

1.1 The Microsoft .Net framework on your PC is missing or is too old
This is the problem when you get errors like:

  • System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
  • System.IO.FileLoadException: Kan bestand of assembly System.Core, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes of een van de afhankelijkheden niet laden. De gegeven assembly-naam of -codebasis is ongeldig. (Uitzondering van HRESULT: 0x80131047)
  • Det gick inte att läsa in System.Net.Cookie Container från sammansättningen System.Net.Version= Culture=Neutral.PublicKeyToken=b03f5f7f11d50a3a
  • System Update Required. Unable to install or run this application. This application requires your system to be updated to Microsof Common Language Runtime Version 4.0.30319.0
The solution: Install the latest framework from the Microsoft website.
On Windows XP: Install
On Windows Vista and Windows 7: Install
Install all updates that come through Windows Update.

1.2 Firefox browser
Firefox does not support ClickOnce.
Try using Internet Explorer once: just for installing RoboBridge. After installing RoboBridge you can go back to Firefox.
Another workaround: install this Firefox add-on:

1.3 Application cache corrupt
The application cache is a part Windows in which applications like RoboBridge can save the user settings.
If you get an error during the check for a new version of RoboBridge that contains "COMException" and "HRESULT: 0x800736B3" this indicates a corruption of this cache.
The resolution is to delete the folder "%userprofile%\Local Settings\Apps". On my Vista machine that is "c:\users\job\Local Settings\Apps" and on my XP machine that is "c:\documents and settings\job\Local Settings\Apps".
 This will remove all settings of all .Net applications! For RoboBridge it means you will have to create your convention card again.
