Could not load file or assembly 'Seagull.Data, Version=11.1.4.1, Culture=neutral, PublicKeyToken=109ff779a1b4cbc7' or one of its dependencies. Access is denied. フォローする

Have you found a solution?  I am running into the same situation.

Have either of you found a solution to this?

We have seen some reports of this issue, but we have not been able to reproduce this issue internally. Generally, one of the following items helps resolve the issue.

1. The Seagull.Data.Core.dll is stored in the BarTender installation directory C:\Program Files\Seagull\BarTender 2019. Make sure the user account that you are running BarTender has full permissions to this directory and file.
2. Manually install the Seagull.Data.Core.dll into the Windows Global Assembly Cache. You can do this by running the following Windows PowerShell script as a local administrator. You may also need to restart your system for this to take effect. You can find more information from Microsoft here.

   #Note that you should be running PowerShell as an Administrator
   [System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
   $publish = New-Object System.EnterpriseServices.Internal.Publish
   $publish.GacInstall("C:\Program Files\Seagull\BarTender 2019\Seagull.Data.Core.dll")

Jasper,

I can confirm option #2 fixed my problem.  Thanks!
