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:
- Download ReSharper 9.1 RTM (full or web installer) from the web site
- Run the installer. It will automatically detect whether you have previous versions installed.
- If the Update option for ReSharper is not pre-selected, select it and proceed with the upgrade installation.
- Forgive us.
We hope that you enjoy the latest update despite this issue.
