Error checking out license, 2.296.2, R20

Received this error when trying to check out a license for pollination with plugin 2.296.2 and on Revit 2020 model.
I have access to the license pool and know that at least one seat was available when I requested it.

Hi @mmeador,

This is a dependency conflict similar to the ones that we have seen in the past. The oldest version of the Revit plugin that I have installed is Revit 2021. Everything works as expected on my end.

There are two possibilities on why you’re getting that error.

  1. You have another add-on installed on Revit 2020 that is using an older version of Annotations assembly. The easiest way to address this is to disable all the other add-ons and see if that resolves the problem.
  2. Revit 2020 itself uses an older version of Annotations. If that’s the case, then we have to create a new build but I suspect this to be the reason.

Can you try the first option and let us know how it goes?

I’m also adding @mingbo here to see if he any other suggestions.

I removed all other add-ins except for Pollination.
Received the same error when trying to retrieve a license.

The areas I needed from this model are simple enough to build without Pollination and not very large.
I should not need a special build for this case.

Hi @mmeador, thank you for testing and being flexible.

I leave this to @mingbo to makes the call about this issue. We have been discussing dropping support for Revit 2020 for some time now.
