If you run VsixInstaller.exe
from the developer command prompt installed with Visual Studio, without parameters, you get a help text message box with this text:
Usage: VSIXInstaller.exe [/quiet] [/admin] [/skuName:name /skuVersion:version] </uninstall:vsixID | vsix_path>
- OPTIONS -
/quiet
Suppresses the UI. Short form is '/q'.
/admin
The extension will be installed to the admin extensions location. Short form is '/a'.
/skuName:<name>
The name of the application to which to install or uninstall the extension. Must be used with /skuVersion. Valid values include:
- Ultimate - (Visual Studio Ultimate Edition)
- Premium - (Visual Studio Premium Edition)
- Pro - (Visual Studio Professional Edition)
- VSLS - (Visual Studio LightSwitch)
- IntegratedShell - (Visual Studio Shell - Integrated Mode)
- VBExpress - (Visual Basic Express)
- VCSExpress - (Visual C# Express)
- VCExpress - (Visual C++ Express)
- VPDExpress - (Visual Studio Express for Windows Phone)
- VSWinExpress - (Visual Studio Express for Windows)
- VWDExpress - (Visual Studio Express for Web)
Isolated Shell names may also be specified. Short form is '/s'.
/skuVersion:<version>
The version of the application to which to install or uninstall the extension, in the form major.minor[.build[.revision]]. Must be used with /skuName. Short form is '/v'.
/uninstall:<vsixID>
Uninstalls the extension with the specified identifier. If /skuName and /skuVersion are not specified, the extension will be uninstalled from all products that contain the extension with the corresponding identifier. Short form is '/u'.
- ARGUMENTS -
<vsix_path>
Path to a valid .vsix file. This argument is invalid when /uninstall is specified.
So, according to this you can do this:
VSIXInstaller.exe /quiet some_extension.vsix
If you want to run this outside the developer command prompt you probably need to execute the right one for the version of Visual Studio you want to install in.
My version is here:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VSIXInstaller.exe
