  Hi All,

  I am using the Wscript shell to check the registry entry in the VBscript. When i am running the code from console it is working but when i run the same through a custom action from an installer. It is giving below error message:

  Error Message:

  ###Info: -2147024894 ::: Invalid root in registry key "HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.6\InstallPath\". :: WshShell.RegRead

  Script used:

  Function readFromRegistry(strRegistryKey, strDefault)

  Dim WSHShell, value, CheckFor, CmdToRun, returnValue

  On Error Resume Next

  err.Clear

  Set WSHShell = CreateObject("WScript.Shell")

  value = WSHShell.RegRead(strRegistryKey)

  if err.number <> 0 then

  readFromRegistry = strDefault

  else

  readFromRegistry = value

  end if

  MsgBox readFromRegistry

  set WSHShell = Nothing

  End Function

  'call readFromRegistry("HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.6\InstallPath\", "NONE")

  call InstallWebdrivers()

  'call readFromRegistry("HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.6\InstallPath\", "NONE")

  Function InstallWebdrivers()

  Dim strCMD, strRootFolder, strPythonInstallPath, strWebMgrPath, strResult

  strPythonInstallPath = readFromRegistry("HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\3.6\InstallPath\", "NONE")

  IF strPythonInstallPath = "NONE" Then

  strPythonInstallPath = readFromRegistry("HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.6\InstallPath\", "NONE")

  End IF

  IF strPythonInstallPath = "NONE" Then

  strPythonInstallPath = readFromRegistry("HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\3.6\InstallPath\", "NONE")

  End IF

  'MsgBox strPythonInstallPath

  strWebMgrPath = strPythonInstallPath & "\Scripts\webdrivermanager.exe"

  strRootFolder = "C:\"

  strCMD = """" & strWebMgrPath & """" & " --linkpath " & strRootFolder & " chrome firefox"

  Wscript.Echo(strCMD)

  'strResult = RunPowerShellCommand(strCMD)

  End Function
