## Additional testing notes

Based on my brief local testing with Visual Studio 2017 Preview versions 15.3.0 Preview 3 and Preview 5, this exact error only affects Visual Studio 2017 Preview version 15.3.0 Preview 4.  In version 15.3.0 Preview 5 and Preview 6, the Xamarin Updater no longer offers _any_ updates (and Preview 3 installs the "Xamarin.Apple SDK" successfully, although it has other complications).  (The absence of _any_ updates for the newer Visual Studio 2017 Preview versions is also a problem, but it means that users won't get far enough into the installation to see the error from Comment 0 any more.)

These issues are all complications due to the .vsix installer versioning scheme for the preview .vsix files provided via the Xamarin Updater extension.  The problems have appeared in the more recent Visual Studio 2017 Preview versions because the current .vsix packages in the Xamarin Updater extension are still the original packages from back on May 10.  In contrast, the latest versions of Visual Studio 2017 Preview include newer built-in versions of the Xamarin components from July 12 and later, and those newer .vsix versions cause an installation mismatch issue for the VSIX Installer when it tries to install the older .vsix packages from May 10 over them.

In short, the Xamarin Live Player and Xamarin IoT previews are temporarily unavailable in Visual Studio 2017 Preview on Windows due to these versioning complications, but work is underway to publish new builds in the Xamarin Updater as soon as possible.  Additional status updates can be followed on [2].

Comment 8 Brendan Zagaeski (Xamarin Team, assistant) 2017-08-10 18:29:13 UTC
This issue is now resolved.  The new updated .vsix packages have been published to the Xamarin Updater extension feed [1].  I will accordingly mark the report as resolved for bookkeeping.

Note that Users wishing to use the Xamarin Live Player will need to be sure to enable the setting under "Tools > Options > Xamarin > Other" as described in the latest information on [2].
