MO gives me installer plugin error on launch

[petrinac1]

Trying to set up ModOrganizer to nod Morrowind. When i go to launch MO it gives me an error that it failed to load "installer_OMOD.dll"

If I load the plugin i receive a large error wall that tells me it's .net issue

If I skip the plugin and go into MO i can add mods to the program but I don't think they get installed into Morrowind's files. I also went through each .dll file and made sure that it wasn't blocked by a firewall. I'm super lost at this point and i can't find any info on what to do

This is also the first time i'm attempting to mod a game and i'm fairly new to PC so i'm a little out of my element. Any help would be extremely welcomed

I'm going to guess you used the archive to install MO2. This problem is typically caused by blocked files.

You should unblock the archive before extracting the files.

This is where I installed it from, is that what you mean?

I did what Silarn said and unblocked the files before extracting and now it works! thank you so much for the help

Sorry i understand this issue is closed now but im having it as well. How exactly do you "unblock an archive". Ive been modding games a while and this is the first i heard of it. Thank you in advance for any help.

First, we strongly recommend that you don't use the archive to install MO2, and instead use the installer, as this isn't the only extra step you'll need when using the archive version. Downloading the installer and installing it is what we recommend you do.

If you're going to ignore that advice, which you shouldn't, unless you have a really good reason, you can unblock files by right-clicking them, opening the Properties window, and checking the Unblock checkbox.

Thank you for the response. I'm a little confused. I'm trying to run Stalker Gamma that comes with MO in it. When I go to play the game and MO opens it gives me the exact same error as @petrinac1 .

I apologize I'm thinking this may need to be a reopened question but since its the exact same error i thought it would be better to get the answer here as it was solved.

Then you're experiencing a bug with STALKER G.A.M.M.A which they need to fix. The archive is specifically intended for projects like that, but they're meant to be responsible for the extra steps that the installer would do. You can send a link to this thread to its maintainers, and tell them a MO2 dev says they're doing something wrong.

They can fix the problems in their PowerShell script by calling Unblock-File on the zip they download before extracting it, and may want to use Add-MPPreference if they're having antivirus false positives (although I think it's long enough since the last MO2 release that the relevant files have probably ended up in Microsoft's database of known safe applications).

[petrinac1]

If i’m not mistaken i fixed the error by reverting to an older driver.

[AnyOldName3]

That couldn't have made any difference to this unless the older driver was incredibly broken and killed part of Windows security.

[Jessed394]

I see, either way ill try to let them know about this issue thank you for the permission. I have had the game before and it ran fine with MO. The only difference now is i have a newer graphics card and many things have now updated in different areas since then. Thank you both @AnyOldName3 and @petrinac1.

I just installed Windows 11. I used the windows uncompress method to extract the mo2 zipped file from GitHub. I received the same error messages. I created another portable instance of mo2 but this time using 7zip like I have always used and it worked. This probably tracks with another reply about 'unblocking' the file, which I never heard over either so don't feel bad. More than likely this is just one more of those things that Microsoft gives you that you never knew you needed. So, Microsoft maybe? blocks some type of files that look suspicious? and 7zip just assumes when you say you want to uncompress a file you want to uncompress all of it.

[AnyOldName3]

Normal people are absolutely not supposed to be 'installing' MO2 from the zip. It's not an installer, so it doesn't install MO2, so the MO2 you get by unzipping it won't work properly. It's just the files so that other tools like Wabbajack have a way to install MO2 if they can't use the installer.

Stop. If you have couple of games and don't want to leave more than enough in the system - zip is more than fine, I use it for months. Just extract it with 7z, anything else like windows one will cause these problems
