 | Command-line switch | Description |
 |---------------------| - |
 | `/ResetSkipPkgs` | Clears all skip loading options that have been added by users who want to avoid loading problematic VSPackages, then starts Visual Studio. The presence of a SkipLoading tag disables the loading of a VSPackage. Clearing the tag re-enables the loading of the VSPackage.<br /><br /> This switch takes no arguments. |
-| `/RootSuffix` | Starts Visual Studio by using an alternate location. The following command is run by the shortcut created by the Visual Studio SDK installer:<br /><br /> `devenv /RootSuffix exp`<br /><br /> In this case, `exp` identifies a location with a particular suffix (for example, `10.0Exp` instead of `10.0`). The experimental instance allows you to debug a VSPackage separately from the instance of Visual Studio that you're using to write code.<br /><br /> This switch can take any string that identifies a location that you've created by using VSRegEx.exe. For more information, see [The Experimental Instance](../extensibility/the-experimental-instance.md). |

The name of the instance must be a valid file name. For more information, see [The Experimental Instance](../extensibility/the-experimental-instance.md). |
 | `/SafeMode` | Launches Visual Studio in safe mode, loading only the default IDE and services. The `/SafeMode` switch prevents all third-party VSPackages from loading when Visual Studio starts, ensuring stable execution.<br /><br /> This switch takes no arguments. |
 | `/Setup` | Forces Visual Studio to merge resource metadata that describes menus, toolbars, and command groups from all available VSPackages. You can only run this command as an administrator. <br /><br /> This switch takes no arguments. The `devenv /Setup` command is typically given as the last step of the installation process. Use of the `/Setup` switch doesn't start the IDE.|
 | `/Splash` | Shows the Visual Studio splash screen, as usual, and then shows a message box before showing the main IDE. The message box lets you study the splash screen (for example, to check for a VSPackage product icon).<br /><br /> This switch takes no arguments. |
