Dynamo doesn't start from Revit after 1.0.0 upgrade


This is my first slightly frustrated post. After updating to 1.0.0 I click on the add-on for Dynamo in Revit and it greys out but does not open. A window theoretically opens (on start bar) but it cannot be activated. I’ve tried everything in this entry which seems to be an almost identical issue on a previous version:


All to no avail. I’ve also bothered my in office IT team for ages and made sure all traces of old versions are deleted before I do re-installs.

Does anyone else have any solutions or had the same issue?

I’ve also checked out this link:


But the forum only allows me to post one link per message

Hi @luke.daviesZ4W5M - We recently changed our installers which might be what is causing the issue for you. How did you “update” to 1.0.0?

Some other people have been having similar issues and have posted on github. Check out this post and let us know if any of the fixes mentioned work for you: https://github.com/DynamoDS/Dynamo/issues/6555

@luke.daviesZ4W5M - did you ever get Dynamo to work for you? Dynamo 1.1 is releasing today, please check it out and let me know if you have issues with install/uninstall.
