Question

I have this Error since i've installed Visual Studio(Community) on my new PC.

Error 1 The build stopped unexpectedly because of an internal failure. System.Text.EncoderFallbackException: Unable to translate Unicode character \uD928 at index 661 to specified code page. at System.Text.EncoderExceptionFallbackBuffer.Fallback(Char charUnknown, Int32 index) at System.Text.EncoderFallbackBuffer.InternalFallback(Char ch, Char*& chars) at System.Text.UTF8Encoding.GetByteCount(Char* chars, Int32 count, EncoderNLS baseEncoder) at System.Text.UTF8Encoding.GetByteCount(String chars) at System.IO.BinaryWriter.Write(String value) at Microsoft.Build.BackEnd.NodePacketTranslator.NodePacketWriteTranslator.TranslateDictionary(Dictionary2& dictionary, IEqualityComparer1 comparer) at Microsoft.Build.Execution.BuildParameters.Microsoft.Build.BackEnd.INodePacketTranslatable.Translate(INodePacketTranslator translator) at Microsoft.Build.BackEnd.NodePacketTranslator.NodePacketWriteTranslator.Translate[T](T& value, NodePacketValueFactory1 factory) at Microsoft.Build.BackEnd.NodeConfiguration.Translate(INodePacketTranslator translator) at Microsoft.Build.BackEnd.NodeProviderOutOfProcBase.NodeContext.SendData(INodePacket packet) at Microsoft.Build.BackEnd.NodeProviderOutOfProc.CreateNode(Int32 nodeId, INodePacketFactory factory, NodeConfiguration configuration) at Microsoft.Build.BackEnd.NodeManager.AttemptCreateNode(INodeProvider nodeProvider, NodeConfiguration nodeConfiguration) at Microsoft.Build.BackEnd.NodeManager.CreateNode(NodeConfiguration configuration, NodeAffinity nodeAffinity) at Microsoft.Build.Execution.BuildManager.PerformSchedulingActions(IEnumerable1 responses) at Microsoft.Build.Execution.BuildManager.HandleNewRequest(Int32 node, BuildRequestBlocker blocker) at Microsoft.Build.Execution.BuildManager.IssueRequestToScheduler(BuildSubmission submission, Boolean allowMainThreadBuild, BuildRequestBlocker blocker) F:\Adam\ProjetVS\TestApplicationWeb1\TestApplicationWeb1\TestApplicationWeb1.csproj TestApplicationWeb1

I sometimes change my Windows Unicode to Japanese. I don't remember if I changed it before or after installing VisualStudio.

Whatever, this is a quite big problem actually. I have some projects on the pot and even a simple new project does not even build. I tried to uninstall & repairs VisualStudio , but the same error remains.

Is my Windows 8 corrupted ?

Oh, also, i found an article on this error, but I don't really get what Scott means by cleaning a certain path ?

Here's the article

What does he mean by cleaning his path ? Which path ?

Please help, Thank you !

SOLVED, Hans Passant posted : (error msb4014: the build stopped unexpectedly because of an internal failure. Restarting VisualStudio doesn't work)

I've seen this exception trace back a few times. Easy to google, just query for "msbuild System.Text.EncoderFallbackException". This blog post is considered the canonical answer afaik.

It is an environmental problem, caused by machines with a corrupt PATH environment variable. Which happens entirely too often, it is a nasty global variable that gets mangled too often by a broken installer.

You fix it with Control Panel > System > Advanced > Environment Variables > System variables > Path. Click Edit and copy the content of the intentionally small text box into a text editor. Clean it up, deleting obviously wrong paths and bad characters. Some paralysis at the usual mess is expected, take no prisoners. Paste it back into the text box. Logoff + Logon to ensure the new value is in effect for all processes.

Thanks Hans, it is finally, resolved.
