I create a new package in SSIS and when I try to run the package, SSIS returns the following error (displayed in a Visual Studio Error Dialog):
"Cannot communicate with the debug host process. The IDtsHost interface is not registered. (Microsoft.DataTransformationServices.VsIntegration"
Environment: VS 2019 with newest SSIS Extension Installed. The package appears to be created correctly and the build succeeds.
The error happens even if the package is trivial "hello world" type of package.
I found no solution to this after a fairly extensive search.
Thanks to EmersioN (https://stackoverflow.com/users/707267/emersion) for the solution. The problem in this case was the selected targeted version of SQL Server. My project was configured to target "SQL Server 2017", but was connected to a server running SQL Server 2012.
If you're seeing this error, this may be the reason.
Go to the properties page of the Integration Services project that contains the affected package. In the Property Pages dialog, navigate to Configuration Properties > General. Under the property group, Deployment Target Version, in the TargetServerVersion property drop-down, select the SQL Server version that matches the one you're connected to.
I just came across this as well in VS2019 SSDT. In my case it was a working SSIS package that after going to sleep for the night, the machine woke up and wouldn't execute the same scripts. These were my steps. Hope they help you or someone else who stumbles across this.
Open each connection within the script, Test Connection and Save
Clean the solution
Rebuild the solution
My context
Working through an SSIS tutorial using SQL Server 2019 Developer (v15.0.2080.9) and VS2019 Community (v16.11.9) to create packages using SSDT (SSIS Projects v3.15).
Packages in VS have executed without issue in the past. I then upgraded my machine from Windows 10 Pro to 11. Now, when running the same - possibly any - package I get the following error:
===================================
Failed to start project (Microsoft Visual Studio)

...and the package does not execute.
What was tried
I tried/checked all 3 answers posted here.
Error persists.
This VS Dev Community's post recommended upgrading the VS extension, SSIS Projects. Since I had the most recent version installed an upgrade was not applicable, so I chose the repair option from the installer.
Error persists.
I then ran a repair on the VS2019 install. This, in turn, required another repair on SSIS Projects. (I still had both installers on my machine which made this easy.)
Error persists.
This MSDN post recommended re-registering DtsDebugHost.exe, failing that, re-installing SQL Server.
I ran the DtsDebugHost.exe /regserver command.
Error persists.
My Solution
I then chose to repair my SQL Server installation instead of re-installing. This was accomplished via the SQL Server Installation Center > Maintenance > Repair option. In my case, I chose the default instance, MSSQLSERVER.
VS now runs without the error and successfully executes the package.
I couldn't say whether my solution was solely based on the repaired SQL Server instance or a combination of other things tried and my last action. So I offer the path I took in the case of the latter.
Aside: The other choices during the SQL Server repair on my system were (1) another server instance, SQLSERVER2019, and (2) "shared components". Selecting either of those may have resolved the issue as well, but I couldn't confirm that.
In Project Property, turn off Azure-Enabled as seen in the image below. Your package will execute afterwards.
I encountered this error after upgrading to Windows 11.
I referred to the post by #steveb and went straight to his solution of repairing SQL Server (SQL Server Installation Center > Maintenance > Repair), without doing any of the other steps he tried.
And that solution worked.
I'm posting this because #steveb said he was unsure if any of his previous steps had affected the ultimate solution, and in my experience they were not necessarily needed.
I'm installing (well trying to) Maximo Asset Management and have already installed MS SQL on a Windows 2008 R2 Server. I have installed Middleware and am now trying to run through the steps to install Maximo 7.5. I have tried Googling this error message however there is only 1 thread on it which has no answer, and the message itself it quite vague and cryptic. Has anyone ever come across this before or could offer any advice on what I should look into to fix it?
I installed SSRS on my computer with the file SSDTBI_x86_ENU.exe. I started to create a report server project which contain tow .rdl file. Now I want to deploy it so I can see my reports in the browser. When I click the start button Visual studio give me an error and say that I have to specify a valid URL. So I went to reporting services configuration manager. My problem is when I enter my server name it says invalid namespace!!
Despite taking -2 for this question, I will answer it because I resolve it and hope that will help somebody someday. It is a problem connected to the version of SQL server express with tools. It didn't allow the deployement of rapports. So I uninstall it and install sql server express with advanced services and every thing magically worked.
I have a VB Windows forms application that uses a mysql database to keep track of everything within the application.. The problem that I know will occur is that most of the applications users will not have MYSQL let alone know how to install it properly... To install the application on the users systems I am using the Visual Studio Setup Installer to handle creation of the msi files.. What needs to happen first is the installer needs to check to see if MYSQL is installed on the host system and verify server name.. If true then import database, if not then install followed by import database... The importing is not the issue here... How do I make the installer install mysql with controlled parameters such as server name, etc, etc. Any ideas on this??? I have hammered google for the past 3 hours looking for bread crumbs on this but to no avail...
Usually existing packages (like the MySQL installer) are added as prerequisites. Visual Studio setup projects do not support custom prerequisite creation. However, this can be done by manually generating the required manifests.
You can find the manifests structure here: http://msdn.microsoft.com/en-us/library/ms229223(VS.80).aspx
These manifests can be generated automatically with the Bootstrapper Manifest Generator tool.
After generating the package manifests, you can add all these files (including the package) in a separate folder in the Visual Studio prerequisites folder, for example:
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\
You can then select the prerequisite in your setup project properties page.
Well... that's a good question. The first thing that pops up in my mind:
You could build the check in your application instead of the installer and warn the user about it. If needed, you could provide another installer to make sure everything is available (MySQL and the database itself).
I hope it helps you further.
Yours sincerely,
Roland
On a clean windows machine I installed Web Dev Express 2008. That also installs SQL Server Express 2008. I just wanted to add SQL Server Management Studio Express (SSMSE) 2008. I had problems, and I'm not the only one:
http://msdn.microsoft.com/en-us/library/ms365247.aspx
The msdn page has a lot of suggestions and a lot of people who say the suggestions don't work, but as Jeff and Joel would say, the forum format doesn't work well at pointing at the definitive answer, so I am hoping the StackOverflow wiki/voting format will be better at having the real solution bubble up to the top.
BTW, what I ended up doing was uninstalling all the 2008 stuff that Web Dev installed, and then I downloaded the 2005 file and that went easy. Possibly, after uninstalling what Web Dev installed I could have been successful with the 2008 stuff too, but i didn't try.
This was all on Windows 7 pro, but the way, but I had a similar traumatic experience on XP.
EDIT1 - Somebody DOWN voted this? But... why? This is a real programming issue that many of struggled with and there is no canonical answer. This is THE place for community vetted/voted canonical answers!
Some quotes from comments at the MSDN download page:
"Thoroghly confusing and no clear Final Answers? Someone needs to summarize the results of the previous postings on this page and put an authoritative stamp on some of the findings and declarations"
"Like everyone else posting here, I have gone through this entire cycle and it is hugely frustrating".
"you have taken something that was working well and had NO need to be this complex and managed to completely confuse everyone that is using it and make it a general PITA"
There are multiple SQL Server Express downloads.
This one is just the Management Studio Express and is what I've always installed when I needed access to a database.
Download the Management Studio tool only and install that.
