I am setting up a new laptop (win10, old one was win7). At my shop, we use a custom task in most of our SSIS packages. When I open an existing package using this task I get an error:

TITLE: Microsoft Visual Studio

The task with the name "Log Start Event" and the creation name "TBSM.Vision.SSIS.LoggingTask.VisionLoggingTask, TBSM.Vision.SSIS.LoggingTask, Version=1.0.0.0, Culture=neutral, PublicKeyToken=ed92d0ee7f09d162" is not registered for use on this computer. Contact Information: Vision Logging Task

------------------------------ BUTTONS:

OK

Running Visual Studio 17, version 15.9.6

At first I thought I messed up the gac, but looks like I didn't:

C:\Windows\System32>gacutil /l TBSM.Vision.SSIS.LoggingTask Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.0 Copyright (c) Microsoft Corporation. All rights reserved.

The Global Assembly Cache contains the following assemblies:
TBSM.Vision.SSIS.LoggingTask, Version=1.0.0.0, Culture=neutral, PublicKeyToken=ed92d0ee7f09d162, processorArchitecture=MSIL

What else am I missing?

There are many possible causes:

(1) TargetServerVersion not adequate

You are selecting a TargetServerVersion which is not relevant to the dll.

GoTo Project Properties >> Configuration Properties >> TargetServerVersion 

Or you have selected a TargetServerVersion that doesn't contains the task dll in the corresponding Task folders.

• SSIS 2012 = C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Task
• SSIS 2014 = C:\Program Files (x86)\Microsoft SQL Server\120\DTS\Task
• SSIS 2016 = C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Task
• SSIS 2017 = C:\Program Files (x86)\Microsoft SQL Server\140\DTS\Task
• SSIS 2019 = C:\Program Files (x86)\Microsoft SQL Server\150\DTS\Task

(2) Registered 32-bit dll

It looks like you registered a 32-bit dll

Try running the package in 32-bit mode:

GoTo Project properties >> Debugging >> Run64BitRuntime = False 

More information at:

• Run an SSIS Package in 32 Bit Mode

Found the problem.

In order to use the custom Task .DLL, you need to put the .DLL file in the ./Task sub-directory, not the ./Pipeline directory.
