Using VSIXInstaller.exe to install programmatically an extension to Visual Studio 2015 and Visual Studio 2017

Answering a question in the MSDN VSX forum today, I have learned another change caused by the new VSIX installer (VSIXInstaller.exe) of Visual Studio 2017 that it is worth documenting here.

As you know, in Visual Studio 2015 only one edition (Community, Professional or Enterprise) could be installed on the same machine. Two or more editions couldn’t coexist at the same time. Given that the Enterprise edition includes the features of the Professional edition and that the Community edition is basically the Professional Edition (without some feature such as CodeLens), the VSIX manifest of your extension could target the “Pro” edition and as such it would be installable on any edition (Community, Professional or Enterprise):

Normally a .VSIX file is installed just double-clicking it, so that the VSIXInstaller.exe application is launched. But if you want to install an extension programatically, the VSIXInstaller.exe application offers a few command-line switches:

Notice the /skuName:<name> option: it allows to specify the exact edition (Enterprise, Premium, Pro, Community, etc.) of Visual Studio where you want to install the extension. Which value you would need to use? It happens that for Visual Studio 2015, you can use “Pro” and the extension will be installed happily not only on Visual Studio 2015 Professional, but also on Visual Studio 2015 Community or  (Updated March 1, see comments section) Visual Studio 2015 Enterprise. For example, installing my MZ-Tools extension on Visual Studio 2015 Enterprise edition with this command line works perfectly:

vsixinstaller.exe /skuName:Pro /skuVersion:14.0 “<path>\MZTools8VSPackage.vsix”

(notice that it recognizes my Enterprise edition as Professional edition).

However, the same is not true for VS 2017. Using this command line to install it on my Visual Studio 2017 Enterprise edition:

vsixinstaller.exe /skuName:Pro /skuVersion:15.0 “<path>\MZTools8VSPackage.vsix”

causes this error:

The following command-line is required, targeting specifically the Enterprise edition:

vsixinstaller.exe /skuName:Enterprise /skuVersion:15.0 “<path>\MZTools8VSPackage.vsix”

So, this is another implication of the new modular setup of Visual Studio 2017 for VSX developers. You can query the installed VS 2017 editions with a new Setup API (sample included).

  1. Hi Carlos,

    I think you will actually not be able to install the extension in VS2015 Community with the /skuName:Pro. In VS2015 the “universal” sku value is Community. The /skuName:Pro will work with all previous VS versions instances though. 🙂
