My operating system is windows 8.1, my anti-virus software is iobit malware fighter. How do I check where MO is installed? The file containing it is on my desktop. I tried running MO as admin, didn't make any difference. The SKSE.ini is .ini and not ini.txt, and is located in the right place. The initial Skyrim.ini and SkyrimPrefs.ini files were created long before I installed MO, unless they need to be re-created for MO to work? I don't know what else to tell you to be honest.
