SED file location is wrong when generate exe using IExpress.exe

Question

I have a project to generate bundled exe using IExpress.exe and run the following command from command prompt

iexpress /n "C:\Users\Desktop\Generation\template.sed"

which invokes the IExpress UI and pasted automatically with incorrect value in the text box for SED location

Incorrect path: C:\WINDOWS\system32"C:\Users\Desktop\Generation\template.sed"

i am wondering why this discrepant. Could any one provide suggestions to fix this.
