Hi. I've been modding Skyrim (AE) for a few years now. Several months ago my laptop died and I had to get a new one and restart all the modding stuff. Anyway, in my old setup, I'd be able to double-click on a mod in the modlist, a box with several tabs would show up, and under "Conflicts" there'd be a list of active textures and meshes. It used to be that I could double-click on one of the .nif files in the Conflicts box and it would then open said file in NifSkope. Now I can't figure out how the heck to get it to do that again. I added NifSkope as an extension in MO2 and when I double-clicked on a .nif file, nothing would happen. I asked for help on the Skyrim Mods Reddit, but the help I got wasn't... great. (I asked once, someone told me there was a setting for that--without telling me what the setting was. I asked them and they haven't replied in a week, so... People, am I right?) I asked again, and someone sort of helped by misunderstanding what I meant and suggesting NIF Preview. It's helpful in many ways, but... When I would double-click on a .nif file before--back on my old laptop--it would open up NifSkope, the actual program. The mesh would be in there with no texture, but visible... vertices and stuff, which were helpful for certain things. Anyone have any idea what I'm talking about? Anyone know a more Nifskope-focused place I could ask, maybe? I'm assuming I did something wrong, but don't know what. I'm also having an issue when I try to open .nif files with Nifskope via going to where the file is located. It does nothing when I double-click it, and when I right-click to select a program to open it with, I get TWO NifSkope options with, like, placeholder icons, and whichever I click on doesn't open anything. Pic attached. Thank you for any help.

Other things to remember: Not knowing MO2 keeps your mods, so when I'm redownloading them I'm not really (I guess?); switching from from Vortex to MO2; upgrading to an SSD which meant I actually did have to start over; etc. I haven't gone full wipe in a while and probably never will; but still, being able to hide a mod on my download list because it's the Oldrim version wouldn't be the worst thing in the world, would it?

Technically I don't HAVE to download my entire modlist again. It's just when I have a lot of mods and it seems like something's broken and I don't know what, because there are multiple candidates, I prefer starting over. Like if my game starts with the messed-up wagon issue, and it doesn't go away by me turning off the last mod I installed, or the second-to-last either, I say 'Lets try that again'. Also, it's amazing what you can accomplish screwing-things-up-wise when you haven't figured out Nemesis yet. Or don't realize a utility is only highly-endorsed because it's 10 years old and doesn't actually work anymore.

I've been working with Skyrim AE, and am generally new to modding and so forth... Long story short, I keep messing up (and learning from my mistakes), then going back to download everything by checking my download history, but that includes things that are NOT COMPATIBLE and cause problems. Either let me delete the mod from my download history, block it in some way so I don't download utilities that are out of date and break everything, or SOMETHING. Or like if two mods do the same thing, but one is so much better than the other--but they have similar names and it's hard to remember which one it was.
