This is not easy in 2013 products. I would start with this...
Starting in 2014, there is a SCCM folder after you create a deployment, there are flags there to easily setup a command line install.
I used ORCA to find my GUID for 2013 C3D.
I created a bat file with the following in it.
"MsiExec.exe /X{33F54798-140F-447E-B199-7FFAD4B3089D} /qn"
It just showed a dos window for a millasecond and nothing happend. According to everything I read, this should have worked. The software is still there and runs correctly. I am at a loss right now.
Thanks for your help. Unfortunately this did not seem to work either. The website says the xml file I need to edit is located in a directory I do not have. I do not know where look. I did try the msiexec.exe command line you suggested but this did not work either.
Any other suggestions?
