An Error Occurred While Validating Hresult
fine for months. However, it has suddenly started refusing to build with the error: HRESULT = '80004005' The setup project contains the output from three projects, and I have narrowed down the issue to one of them. I have found a few questions here with this same issue and have tried them all, namely: Removed projects and re-added to the solution Removed all references and re-added If I right click the project output in the an error occurred while validating the server dns setup project and select 'View Dependencies' the list is empty which seems to be a symptom others have found with this issue. However, despite several hours of googling, I have not managed to resolve it. visual-studio-2008 share|improve this question edited Oct 22 '13 at 8:04 Peter Mortensen 10.2k1369107 asked Mar 10 '11 at 20:56 Macros 5,37312351 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted Ok - I finally found the answer.

HRESULT = '80004005'" (And Microsoft wins an award to clarity.) I Google to find that a small army of developers have had the same problem. Really the error http://stackoverflow.com/questions/3629499/hresult-80004005-in-visual-studio-2008-setup-project should read: "Could not find a reference in one of your projects." Everyone states (even on StackOverflow) how to find the project with the broken reference: Remove all outputs from your setup project. Add each project output individually until you see the error appear. I do that, find the 80004005 error appears for my main executable project and the main class library project. Since the main executable project references the main class library project, I assume the issue is in the main class library project. Once you find the project, people say to remove all references, and re-add them (this fixes any pathing issues that seem to be the primary cause of this error). In fact, I've done it to all projects in the solution, just for good measure. I still get the 80004005 error. I have Googled for about five hours, I have not found any other suggested solutions. I'm almost down to remaking all 7 projects in this solution, which will take me a hours to do, and does not guarantee a result. Suggestions are welcome before I begin sacrificing a small cudd Help Receive Real-Time Help Create a Freelance Project Hire for a Full Time Job Ways to Get Help Ask a Question Ask for Help Receive Real-Time Help Create a Freelance Project Hire for https://www.experts-exchange.com/questions/24741644/An-error-occurred-while-validating-HRESULT-'80004005'.html a Full Time Job Ways to Get Help Expand Search Submit Close Search Login Join Today Products BackProducts Gigs Live Careers Vendor Services Groups Website Testing Store Headlines Experts Exchange > http://jepsonsblog.blogspot.com/2010/12/error-occurred-while-validating-hresult.html Questions > An error occurred while validating.

HRESULT = '80004005' Posted on 2009-09-17 .NET Programming Visual Basic.NET 2 Verified error occurred Solutions 4 Comments 3,802 Views Last Modified: 2013-11-26 I've got an existing setup project that I'm trying to add some projects to. I've added the projects to the solution, and they all build without error. I'm having problems adding their output to the setup project. When I do, I'm getting "An error occurred while validating. HRESULT = '80004005'" error. The dependencies for some error occurred while of the newly added projects are not being detected and added to the setup project. If I look at the properties dialog for the primary output, I can see under KeyOutput all the dependencies, but some of them are marked with an exclamation mark. In the Dependencies property is listed "(None)." I've tried adding the assemblies to the project folder, but still get the above error when I try to build. 0 Question by:PaulHews Facebook Twitter LinkedIn Google LVL 38 Best Solution byPaulHews I was having this error all yesterday, including just before I shut everything down.

There are no project references that are not contained in the soluti to build a Deployment package. I also noticed that my deployment package showed no Detected References anymore. The weird thing was, that my solution build properly and I could even run the software. It was just the deployment package that was producing errors. As I found, the first thing to check is missing references. If they are not in use in the code, debugging the project will not produce any errors, building the deployment will. This also includes references to other projects, which are not included in the solution. If not pointing directly to the pre-built dll, these will produce problems. For me though, this did not solve my problem, but I did find something else that caught my eye; during building, the output was showing: Project file contains ToolsVersion="4.0", which is not supported by this version of MSBuild. Treating the project as if it had ToolsVersion="3.5" After some searching, I discovered that one of my colleagues had opened the project (which is used in various solutions) in Visual Studio 2010 (which changed the csproj file) and checked it in, rather than using the VS 2010 version of the csproj file.After rolling back this csproj file (and some others with the same problem), I checked my build output, and saw that it didn't show this ToolsVersion warning anymore.After this, the deployment package built as expected. It even shows its Detected References properly again. If you don't have any means of reverting to an older version, you can also just open the csproj file with any text editor (may I recommend notepad++, a very good free text editor) and do a find and replace onToolsVersion="4.0", to replace it withToolsVersion="3.5". Make a backup of your files though, just in case. Posted by Michael Jepson at 09:49 Email This BlogThis!
