Some more info...
First of all, thank you for placing this post. The quick root methods like Framaroot, Kingo App and KingRoot do not work on the SM-G532F/M/G.
Everything worked, except for the part where ADB Sideload ran to install SU.zip.
I got the message "Device not found" and when I ran Root Checker Pro, it said root was not properly installed - which is obvious without SU.
This was my solution (Under Windows 7 Ultimate):
1. I searched (WINKEY + F) for 'SU.ZIP' and found it under 'USERS\%MY NAME%\APPDATA\LOCAL...'. You may have to enable 'Show hidden files and folders' to find it. Do this from Windows Explorer (WINKEY + E), press ALT, select TOOLS | FOLDER OPTIONS. Select the VIEW tab, then choose radio button 'Show hidden files, folders and drives' and select OK.
2. Copied this 'SU.ZIP' file to my device's SD Card root folder via USB connection.
3. Shut down my phone and rebooted into TWRP (VOLUME UP + HOME + POWER).
4. Tapped INSTALL in TWRP and found the 'SU.ZIP' file and installed it.
5. Restarted the phone and ran Root Checker Pro again.... VOILA!!
I hope this can be of some help to someone.
