The application has failed to start because its side-by-side configuration is incorrect

Question

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembl y 'TheLibrary, Version=1.2.3905.36284, Culture=neutral, PublicKeyToken=14 04827c3a8f2601' or one of its dependencies.

When I look at the event log, I get this error.

Activation context generation failed for "C:\project\Debug\MyLibrary.dll". Dependent Assembly Microsoft.VC90.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8" could not be found. Please use sxstrace.exe for detailed diagnosis.

I used sxstrace to log the error and here is the result:

Any ideas?

Answer 1

Simply download chrome installer and run without uninstalling older version of chrome. It will automatically FIX the issue

Answer 2

Following this answer, I was able to resolve the same on Microsoft Server 2019 issue by:

1. Uninstalling Visual Studio and Microsoft C++ redistributable versions 2010 and above.
2. Re-installing Microsoft C++ redistributable versions 2010 and above in ascending order
3. Re-installing Visual Studio.

I hope this works for someone too.

Answer 3

This is usually an error in App.config file.

Sometimes it happens that you just put an invalid tag or your XML is not of a valid format.

Try checking XML with some XML online validator.

Regarding the allowed tags, here you can find more:

https://learn.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/

If something from your App.config file is not present in the documentation, then it’s probably supposed to be placed in another part of the configuration. For example, in the app.manifest file. You can even google about freshly added code, like some tag or attribute, and figure out the error by comparing how the code you have aligns with your search results. This is a common error to accidentally switch files or mistype a tag.

In my case, I was working with a console application which is build in c# and I was using VS 2017. I tried to publish the code by right clicking on the project and select the publish option and then configure the required settings. it didn't published the exe on configured path but whenever I tried to compile or tried to build the application, I was getting this kind of error. I was googling that error message and I came across this question. This answer may seems irrelevant to the question but still I am posting my answer for the folks like me who got here because of facing problem like mine. So I found the salutation for my problem as below steps :

1. Go to the project file, right click on it
2. go to the properties options
3. go to the signing option
4. uncheck the checkbox named as 'Sign the ClickOnce manifests' its done. Now when I tried to build the console application again, it showed me a warning message, which I have ignored and it got build successfully, and working fine. I have shared whatever I had tried, trying to help here for people like me. Thanks

Answer 5

I wanted to pin-point one more reason why this error could arise: wrong encoding of *.config file.

The file needs to be in UTF-8, while you can actually get ANSI accidentally nowadays by creating configuration file manually using notepad.exe.

Answer 6

I found side by side error there is a mismatched or system error in app.config file. find bug in your app.config file correct it.

Answer 7

I had this issue and it was a simple problem with the version value in assemblyIdentity element of the app.manifest file. Apparently version must have all four numbers (unless assemblyIdentity is ignored which is the case if the manifest is embedded).

So the fix here:

<assemblyIdentity name="MyApplication" version="1.0.1" publicKeyToken="D3567E058552E2DF" type="win32" processorArchitecture="x86" />

is to set

version="1.0.1.0"

After that, everything was hunky-dory.

Answer 8

Make sure that you don't have misplaced configurations, like an <httpsTransport> within an http web service binding.

Answer 9

This is marked C#, so I'll give the C# answer: Something has mangled your projectname.exe.config file.

Pull it up in a text editor and chances are something won't be closed properly or there will be a few garbage characters at the end. You can figure out why that happened later. But for now, just fix it and you'll be able to launch.

Answer 10

We've just had this exact same error but the cause was so misleading compared to the error it's hopefully worth adding here as it comes top on google...

The "The application has failed to start because its side-by-side configuration is incorrect" error was occurring when starting a windows service. In our instance this was caused by the services application.config xml file not being valid - someone had edited it manually and pasted in an extra closing tag. Amending this resolved the "not related in any way whatsoever" error message.

The quickest way to check this would be to paste the xml file into one of the many on-line xml validators free on the web.

Answer 11

For real checking if you are using Windows 7 (must be same for 8 and Vista)

Open from control panel system Administrative tool and select event viewer

Click windows logs-> Application

Find your error log under the column side-by-side

Note the line number where the error occurs.

Then with a editor such write or notepad open yourfilename.exe.manifest

Then from line number </ to /> delete the lines and save the file

Your problem is resolved.

Answer 12

You can just delete the manifest file from your application path, then the executable will work properly,

Answer 13

Dependent Assembly Microsoft.VC90.DebugCRT,... could not be found

Yes, that can only be found on a machine that has Visual Studio installed. The DebugCRT is not distributable. And it doesn't make sense to write C or C++ code and deploy the debug build for it, it is a lot slower.

Deploy the Release build version of your DLL. And the VC++ Libraries, one of the check boxes in the Prerequisites of a Setup project.
