jake6353 Posted October 7, 2018 Share Posted October 7, 2018 I've had this problem where an error shows up whenever I try and install any mod that isn't already installed. I've already installed NVSE, and I can't seem to find any solution on the forum. I really don't know what to do, I've installed NV before and modded it but have never had a problem like this before. Thanks for any help. Link to comment Share on other sites More sharing options...
dubiousintent Posted October 7, 2018 Share Posted October 7, 2018 The error report is basically saying the "Nexus Client" security protocol failed. What "mod manager" are you using? I'm guessing NMM, in which case this appears to be related to the following: As of 08 May 2018, the Nexus has changed some site security to come into compliance with the new "European Union General Data Protection Regulation" (EU GDPR) rules. This breaks older versions of NMM and other tools using the older unsecured API. It is usually reported as being "blocked by the Windows firewall" or causing a "script" or "W3C XML Schema" error installing mods. You will need to update it from NMM on GitHub. Check the version numbers between those sites and use the latest release. Please see this Nexus site news article for details. Edit: As of 13 May 2019 all "workarounds" that depend upon continued use of the old API will no longer function. That API has been removed, as previously announced more than two years ago. This includes but is not limited to:Nexus Mod Manager v0.65.11 and lowerMod Organiser 2 v2.1 and lowerMod Organizer 1This only affects their ability to login to and automate the download from the Nexus site. Some people are finding that even after updating NMM to v0.65.4 they still get a "script exception" message when installing some mods (such as UIO and MCM). This seems to be resolved by this suggestion from user ElysianMod:* Run NMM as an "Administrator privileges" account.* Go to NMM "Settings".* Enable "Add Shell Extensions for Supported File Types".* Then restart NMM.(Supposedly this fix is included in "unofficial" update v0.65.7 and later to NMM on GitHub.) -Dubious- Link to comment Share on other sites More sharing options...
jake6353 Posted October 7, 2018 Author Share Posted October 7, 2018 Yes, thank you the "Add Shell Extensions for Supported File Types" helped with some of the mods and the update had allowed me to finish the install of the rest. Thank you for your help. Link to comment Share on other sites More sharing options...
