Error occur when install application which packaged with CefSharp.Wpf.dll using MSIX Packaging Tool.Below is the errors: 1>C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64\MakePri.exe New -ProjectRoot obj\x64\Release\PackageLayout\ -ConfigXml obj\x64\Release\filemap.priconfig.xml -OutputFile obj\x64\Release\filemap.pri -IndexName 1be397bb-8ae9-4452-9549-7bcbbde828d9 -MappingFile AppX -Verbose -Overwrite

Troubleshotting

From the output of error, we know that the error occur during the below command. In the command, we know that filemap.priconfig.xml is an input file for MakePri.exe. So there should be some error in the xml file or other temp files in the processing. After checked the xml, we did not find any error.

C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64\MakePri.exe New -ProjectRoot obj\x64\Release\PackageLayout\ -ConfigXml obj\x64\Release\filemap.priconfig.xml -OutputFile obj\x64\Release\filemap.pri -IndexName 1be397bb-8ae9-4452-9549-7bcbbde828d9 -MappingFile AppX -Verbose -Overwrite  

When we get this type of issue, we can change the “MSBuild project build log file verbosity” level from Minimal to Normal/Detail/Dianostic. So that we can get more details about the error.

Note: Get more details about MSBuild project build log file verbosity level

After enable the Dianostic log, we will get the context of target error. For current issue, we will get below output from build log. So we check the file of filtered.package.layout.resfiles.

1>PRI222: 0xdef00001 - Unspecified error occurred.

In the file of filtered.package.layout.resfiles, there are several path list below. We guessed it should the RCA.

Main\.\cef.pak
Main\.\cef_100_percent.pak
Main\.\cef_200_percent.pak
Main\.\cef_extensions.pak
Main\.\CefSharp.BrowserSubprocess.Core.dll
Main\.\CefSharp.BrowserSubprocess.exe

Main\.\README.txt
Main\.\snapshot_blob.bin
Main\.\swiftshader\libEGL.dll
Main\.\swiftshader\libGLESv2.dll
Main\.\v8_context_snapshot.bin

So we search “Main\.\” in the building log, we got below errors:

1>Creating hard link to copy "C:\Users\xxxx\.nuget\packages\cef.redist.x64\83.4.2\CEF\cef.pak" to "obj\x64\Release\PackageLayout\Main\.  \cef.pak".

The system cannot move the file to a different disk     drive. (Exception from HRESULT: 0x80070011)

Then we replaced all “Main\.\” to “Main\” and then mannually run below command: The command will be successfully competed.

Solution

After figuring out the RCA, we can workaround the issue by adding a custom task to remove these unexpected string. Below is the steps:

Copy filtered.package.layout.resfiles to your Setup project folder;
Replace .\ to \

Add below code to your setup project configuration

<Target Name="CustomPriFileGeneration" AfterTargets="_CreatePriConfigXmlForMainPackageFileMap" Condition=" '$(Configuration)'=='Release' ">
<Copy SourceFiles="$(ProjectDir)filtered.package.layout.resfiles" DestinationFolder="$(BaseIntermediateOutputPath)\$(Platform)\$(Configuration)" />
</Target>
