Problem with registry key

Hello , I would like to change registry key using vbs  , but i can't declare value . Every time i try to do this script return with 800a0400 error code  .

This what i have in script :

Dim strNewSignature,test,strRFSignature,WshShell
test = "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\9375CFF0413111d3B88A00104B2A6676\00000002\test"

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.RegWrite test, "4800460047000000","REG_BINARY"

I have tried to  import reg file but still nothing  . Error code : 80041002

set oFile  = CreateObject("scripting.FileSystemObject")  
set oShell = CreateObject("wscript.shell")
sRegFile = "C:\Users\user\Desktop\signature\registry.REG"
if oFile.FileExists(sregfile) then
iReturn = oShell.Run("regedit.exe" & sRegFile)
if iReturn <> 0 then
wscript.echo "Import Reg Settings Failed! " & err.number & ":" & err.description
end if
else
wscript.echo "Registry Import Failed."
end if
set ofile = nothing
set oshell = nothing

My reg file :

[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\9375CFF0413111d3B88A00104B2A6676\00000002]

"New Signature"=hex:48,00,46,00,47,00,00,00
"Reply-Forward Signature"=hex:48,00,46,00,47,00,00,00

Can You please help my solve it .
 
 

Which specific line gives you which error?

And also, WScript.Createobject typically should just be CreateObject.

Using WScript.CreateObject() or just CreateObject() shouldn't make a difference. However, AFAIK writing REG_BINARY values via RegWrite() supports only Integer or Long arguments. "4800460047000000" (even if it's implicitly converted) is far beyond the valid range of a Long value (-2147483648 to 2147483647). The error code could also indicate a number of other issues, though, so the actual error message and the line where the error occurs would indeed be helpful.
