问题:

I have SQL Server 2012, SSIS, SSDT and Visual Studio 2010. I can create a new SSIS package and add a Script Task, but if I attempt to open the Script Editor for that Script Task I get the following error:

TITLE: Microsoft Visual Studio
------------------------------

Cannot show Visual Studio 2010 Tools for Applications editor.

------------------------------
ADDITIONAL INFORMATION:

Could not load file or assembly 'Microsoft.VisualStudio.Tools.Applications.Core, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. (mscorlib)

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

OK
------------------------------

From my own investigation into this error, I found that Visual Studio Tools for Applications appears to be a part of MS Office 2007 and higher. This seemed like an odd dependency for to have, but I installed MS Office 2010 just for grins. It didn't change anything. What else should I try?

You will also get this error, if you are trying to debug a script task in VS 2010 and Run64BitRuntime is set to true. In order to debug, set it to false.

I was getting this error and nothing I came across corrected the problem until I logged off as my normal user and logged in as my local admin user. Once I logged in as an admin I could edit the script in my package. Once I logged back in as my regular user the edit script button worked for it too.

I assume it needed to register the assembly on the first launch and couldn't with my regular domain user.

I also got this same error when trying to open the Script Editor, but for a different reason. Not sure how it happened, but I had 3 copies of VSTA (different versions) installed. Once I removed all of them and re-installed SQL Server 2012, problem solved. Hope that helps.

For me the solution was:

close bids (I'm on 2008r2)
reopen
edit the script (it allowed me to edit it once after restarting bids)
delete all breakpoints
make a trivial change, such as adding a blank line
save

That solved it for me.

This worked for me without doing any kind uninstall.

My environment: Microsoft Visual Studio 9.0 (2008)

Solution:

Go to cd "C:\program files (x86)\microsoft visual studio 9.0\common7\ide\"
Execute command vsta.exe /setup /hostid SSIS_ScriptTask. This will open VSTA with blank project. Let it open and then close it.
Execute command vsta.exe /setup /hostid SSIS_ScriptComponent. This will open VSTA with blank project. Let it open and then close it.
Open your solution/packages that contains the script task.
Click Edit button in Script task and it should open now. Just in case if it dont, I would suggest to keep the blank vsta of step 2 & 3 open and then click the Edit button in script task.

Took almost two hours and thankfully it worked for me. I did not have admin right to perform all that nasty uninstall and registry edit solutions.

Hope it helps someone!!!

Cannot show Visual Studio 2010 Tools for Applications editor.

Just follow the below solution:

Go to SQL Server Setup folder.
Inside that folder "redist".
Under that one more folder "VSTA".
Under VSTA folder "X86" and "X64"
Install the VSTA_RT30.
It works fine.

I figured out my problem this morning. When I uninstalled SQL Server 2012 (and the remnants of 2008 left behind when I upgraded last month) I also uninstalled 3 packages that were actually part of Visual Studio 2010. Had I not done this, a reinstallation of SQL Server 2012 would probably have done the trick, but instead I found new errors. When I reinstalled these 3 packages from the Visual Studio 2010 distribution media, everything started working.

The 3 packages in question were:
