Hello group I'm not sure I'm posting where I should be posting. If so, I am sorry as it is not my intention to do so. I am at a loss. I finished all the steps of STEP - CORE except the FNIS part. I have downloaded the FNIS Behavior V5_2 -- ALWAYS necessary mod and installed it with the Mod Organizer. I did so by clicking the ''Install a new mod from an archive'' button. Then, when the window saying ''No game data on top level'' appeared, I right-clicked the ''Data'' folder and chose ''Set Data directory'' then clicked Ok. I then added the GenerateFNISforusers executable through the Data tab in the right pane. The problem is, when I try to run it, it just doesn't. Here's a screenshot of what happens Here's the full error code : Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: generatefnisforusers.exe Problem Signature 02: 5.0.0.0 Problem Signature 03: 545b8ae4 Problem Signature 04: System.Drawing Problem Signature 05: 4.0.30319.18408 Problem Signature 06: 52311178 Problem Signature 07: 67f Problem Signature 08: 6c Problem Signature 09: System.InvalidOperationException OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 4105 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 It does that if I start MO in admin mode. I have an up-to-date .NET Framework. Uninstalled and reinstalled it just to be sure. Other than that, I have no idea what could be the problem. Please help, this is starting to make me lose my mind.
