Updating from previous versions of ReSharper to 9.1 from within Visual Studio

Hello everyone,

Due to an unforeseen technical issue, updating from ReSharper 9.0.1 or ReSharper 9.1 EAP builds to ReSharper 9.1 RTM fails if you try to update from within ReSharper (via ReSharper | Help | Check for Updates). We apologize for the inconvenience that this issue might cause you and recommend the following workaround:

  1. Download ReSharper 9.1 RTM (full or web installer) from the web site
  2. Run the installer. It will automatically detect whether you have previous versions installed.
  3. If the Update option for ReSharper is not pre-selected, select it and proceed with the upgrade installation.
  4. Forgive us.

We hope that you enjoy the latest update despite this issue.

    I also needed to run the installer from outside of Visual Studio. But even after running it twice, I still had 9.0 Update 1 in VS. Only after uninstalling JetBrains Tools Platform completely and running a clean install I was able to use 9.1.

    Heya,

    My office has ReSharper 8.1, which I installed to VS2012. I followed the instructions above, but there was no Update option. After it installed, it looks like I have the 9.1 eval version. I tried using the license username+key combo I was given, but the Manage License Keys dialogue says “License to version 8.0 not acceptable”.

    How do I upgrade from 8.1 to 9.1 with our licenses?

    Thanks!

      Hello,

      Ability to upgrade using existing license depends on its type and date it was issued. Please contact sales@jetbrains.com for assistance on your particular issue.

        ReSharper supports Visual Studio 2015 starting from version 9. If your license included subscription which was valid at least till December, 2014, it might allow you upgrading to version 9. Otherwise you will need to purchase an upgrade to it. Please contact sales@jetbrains.com for further investigations on the issue.
