Bug ID: 48521
           Summary: StaxRip throes errors: Win32Exception (2.0.6.0)
                    Invalid function  System.ComponentModel.Win32Exception
                    (0x80004005): Invalid function
           Product: Wine
           Version: 5.0
          Hardware: x86
               URL: https://github.com/staxrip/staxrip/releases
                OS: Linux
            Status: NEW
          Keywords: dotnet, download, source
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs@winehq.org
          Reporter: xerox.xerox2000x@gmail.com
      Distribution: Debian
Steps to reproduce:
Use Staging (workaround https://bugs.winehq.org/show_bug.cgi?id=45868) and do
- winetricks -q dotnet40 dotnet48
- Invoke like ''wine start /unix /home/louis/StaxRip.exe'' otherwise you run
into 
https://bugs.winehq.org/show_bug.cgi?id=48503
Try open an avi, it`ll tell you to install AviSynth, let it complete, then try
convert it; In the end an errormessage pops up:
Win32Exception (2.0.6.0)

The source is available from github:
Public Class PowerRequest
    Private Shared CurrentPowerRequest As IntPtr
Shared Sub SuppressStandby()
        If CurrentPowerRequest <> IntPtr.Zero Then
            PowerClearRequest(CurrentPowerRequest,

            CurrentPowerRequest = IntPtr.Zero
        End If
Dim pContext As POWER_REQUEST_CONTEXT
        pContext.Flags = &H1 'POWER_REQUEST_CONTEXT_SIMPLE_STRING

                CurrentPowerRequest = IntPtr.Zero
                Dim err = Marshal.GetLastWin32Error()
                If err <> 0 Then Throw New Win32Exception(err)
            Else
                CurrentPowerRequest = IntPtr.Zero
            End If
        End If
    End Sub
Enum PowerRequestType
        PowerRequestDisplayRequired
        PowerRequestSystemRequired
        PowerRequestAwayModeRequired
        PowerRequestExecutionRequired
    End Enum
<DllImport("kernel32.dll", SetLastError:=True)>
    Shared Function PowerCreateRequest(ByRef Context As POWER_REQUEST_CONTEXT)
As IntPtr
    End Function
<DllImport("kernel32.dll", SetLastError:=True)>
    Shared Function PowerSetRequest(PowerRequestHandle As IntPtr, RequestType
As PowerRequestType) As Boolean
    End Function
<DllImport("kernel32.dll", SetLastError:=True)>
    Shared Function PowerClearRequest(PowerRequestHandle As IntPtr, RequestType
As PowerRequestType) As Boolean
    End Function
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Unicode)>
    Structure POWER_REQUEST_CONTEXT
        Public Version As UInt32
        Public Flags As UInt32
        <MarshalAs(UnmanagedType.LPWStr)>
        Public SimpleReasonString As String
    End Structure
End Class
Returning STATUS_SUCCESS for Nt{Create,Set,Clear}PowerRequest gets rid of the
errors. AFAICT it should be pretty safe to just return success from these three
functions, right?
Relevant console-output:

009c:fixme:ntdll:NtSetPowerRequest (0x110ea80, 1): stub
