Suspicion from [Crash after update to “2.0.5.1 (2.0.5.1\_beta\_2020-01-18)”](https://forum.duplicati.com/t/crash-after-update-to-2-0-5-1-2-0-5-1-beta-2020-01-18/8983/5) is further confirmed. Update from original .msi install of [v2.0.2.1-2.0.2.1\_beta\_2017-08-01](https://github.com/duplicati/duplicati/releases/tag/v2.0.2.1-2.0.2.1_beta_2017-08-01) to 2.0.5.1 does not work. Reason is probably that the 2.0.2.1 design was replaced with a different one that is the default: [v2.0.2.11-2.0.2.11\_canary\_2017-10-20](https://github.com/duplicati/duplicati/releases/tag/v2.0.2.11-2.0.2.11_canary_2017-10-20) > Changed the way the auto-updater works. It now spawns a new version of the executable instead of attempting to run it in an AppDomain Look in `C:\Program Files\Duplicati 2\changelog.txt` to see original .msi install version. Non-Windows systems will probably reveal Duplicati’s install location in /usr/bin/duplicati script. Web UI `BaseVersionName` will also show this to you, if you still have a web UI that’s working… Among Beta releases, [v2.0.3.3-2.0.3.3\_beta\_2018-04-02](https://github.com/duplicati/duplicati/releases/tag/v2.0.3.3-2.0.3.3_beta_2018-04-02) is the first that can update to 2.0.5.1. Old releases should be uninstalled for manual update from the .msi installer to avoid this issue. Non-Windows systems should do the equivalent with package tools, not Duplicati autoupdater. --- _[View the full topic](https://forum.duplicati.com/t/installed-new-version-now-duplicati-wont-run/8918)._
