Question : user input masking method in VBscript in Win7

I am writing a vbscript to siliently install a program from a network share. So what it is does is to authenticate the user by prompting the user for credential, then map a network share using the supplied credential as parameter and run the installer silently. The script is running properly in XP but not Windows 7. The reason being is that I used the scriptpw.password method to mask the password info. and this method is no longer supported in win7.  I know the get-credential/read-host cmdlet would do the same but I don't want to use PS script as it requires me to change the script execution policy before hand. I tried calling the cmdlets from within the existing script and the parameter didn't appeared to be passable as they are in different command processor. Any suggestion on how to mask password info. with vbscript in Win7? I do want to run the script in cscript but not wscript and I don't want to use any 3rd thirty utility to do the job.  Thanks
