window7 wpf程序打不开问题排查及处理

部署到客户服务器后，现场反馈打不开软件

1.查看事件查看器报错 

Description: A .NET application failed. Application: DataCollectionClient.exe Path: C:\Users\Administrator\Desktop\***.exe Message: The application to execute does not exist: 'C:\Users\Administrator\Desktop\***.dll'.

 后面查看桌面程序，发现不是快捷方式，是exe，但是目前打包exe是带支持dll的，找到程序包所在实际目录，重新启动，仍未打开 ，再次查看事件查看器

2.事件查看器报错

Description: A .NET application failed. Application: DataCollectionClient.exe Path: C:\Users\Administrator\Desktop\mes\DataCollectionClient_202505211742\DataCollectionClient.exe Message: Failed to load the dll from [C:\Program Files\dotnet\host\fxr\6.0.36\hostfxr.dll], HRESULT: 0x80070057 The library hostfxr.dll was found, but loading it from C:\Program Files\dotnet\host\fxr\6.0.36\hostfxr.dll failed - Installing .NET prerequisites might help resolve this problem. https://go.microsoft.com/fwlink/?linkid=798306

根据事件查看器报错，打开链接，找到我windows7对应环境及安装包，安装后重启

3.注意事项

在我排查前，电脑已安装对应 net环境，所以安装其他补丁后成功，未安装环境的注意需先安装对应net环境
