Run an external executable from a notebook?

Dear All,
I bought a tool that can convert a TDMS file in a CSV file. I need it to open some LabView data and process it with Mathematica.
From the Windows Command Prompt I have to type:

“C:\Program Files (x86)\WhiterockSoftware\TdmstoCsv\TdmstoCsv.exe” c:\temp\myfile.tdms c:\temp\myresultfile.csv

In effect, it works. I tried to call this command directly from my notebook with this script:

RunProcess[{"cmd", {"\"C:\Program Files \(x86)\WhiterockSoftware\TdmstoCsv\TdmstoCsv.exe\" C:\Users\Me\Documents\file1.tdms C:\Users\Me\Documents\file1.csv"}},"ExitCode"]

It does not work.
Where is my error?

Thank you very much for your help

Why is there a \ before C:?

 \C:\Users\Me\Documents\file1.tdms

Thank you Rohit for your reply.
It was a transcription error. there is not a \ before C.
The code is

RunProcess[{“cmd”, {“"C:\Program Files (x86)\WhiterockSoftware\TdmstoCsv\TdmstoCsv.exe" C:\Users\Me\Documents\file1.tdms C:\Users\Me\Documents\file1.csv”}},“ExitCode”]

but it does not work

Thank you!
