how to retrieve exitcode for adobepatchinstaller.exe in a vbs script ?

Hi Guys, I made an automatic installation vbs script to update adobeCC.

For this, i follow the stop below:

1- I retrieve updates from adobe website via remoteupdatemanager --action=download

2- I unzip archives in a target folder

3- In this folder, I am searching all .exe (usually adobepatchinstaller.exe) and execute it.

4- I retrieve the exitcode to know errors.

So, the commandline i use is either

rc=objshell.run(mycommand,,true)

rc=objshell.exec(mycommand)

On the last command, i retrieve the exitcode with rc.exitcode.

In any cases, rc = 0 (even when the is an error).

What I mean is adobepatchinstaller execute a setup.exe or set-up.exe to install updates.

To finish, my question is how to retrieve the correct RC from this exe?
