xHEINZx Posted May 3, 2019 Share Posted May 3, 2019 This is a developing situation, so solutions are trickling in. 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.-Dubious-It worked perfectly. Thank you! Link to comment Share on other sites More sharing options...
jinuoka Posted July 2, 2019 Share Posted July 2, 2019 Hello, i've already tried all the solutions you all gave but none of it can solved mine.There's no Add Shell Extensions for Supported File in my NMM Link to comment Share on other sites More sharing options...
dubiousintent Posted July 2, 2019 Share Posted July 2, 2019 Suggest you need to update your version to the latest NMM on GitHub. The "settings" option appears as a "double wheel gear" icon.(Ignore the "Check this box" part in the lower portion of the image, which was found online related to a different problem. The line you want is just above it.) NOTE: Did you install Steam to it's default location? If so, please see the wiki "Installing Games on Windows Vista+" article for why the original default Steam behavior of installing games to the "C:\Program Files" or "C:\Program Files(x86)" folder tree was bad (they learned better, and don't do that any more); and why "disabling UAC and running as Administrator" is NOT sufficient, with instructions how to move it. This is the single most important thing you can do to fix and protect yourself against problems in the future. As much of a PITA as that is, it's never going to be any easier than now. System updates often cause issues with games installed to these folder trees. Please see the 'Restoring to "Vanilla"' section of the wiki "FNV General Mod Use Advice" article as well. I recommend anyone read the entire "FNV General Mod Use Advice" article to understand the differences between this game and others you may have experience with; especially if this is your first attempt to play a modded FNV or it's been more than a year since you last did so. -Dubious- Link to comment Share on other sites More sharing options...
flaby Posted October 31, 2019 Share Posted October 31, 2019 https://imgur.com/a/oclPl1W Have tried moving steam out of program files as well as checking the shell extension boxes and running nmm in administrator and running on the latest version but I just cannot seem to get mcm to install it gets half way and then that error message pops up and it only happens to mcm any other suggestions?

dubiousintent Posted November 1, 2019 Share Posted November 1, 2019 Double check you have enough disk space. That has frustrated more than one experienced user. As you did move Steam out of the default location, then likely any "security" access privilege problem is one of "File and Folder permissions" on the parent "root" folder under which you installed the games. If this is not set correctly to allow at least "System", "Administrators", and "Users" to have "Full Control" then you can't overwrite other files or make changes. You then (while logged in as an "Administrator Account") need to enable the "Properties | Security | Advanced | Change Permissions" setting of the parent folder to enable the box: "Replace all child object permissions with inheritable permissions from this object", so those changes get applied to the existing files and sub-folders. Make sure you have all "prerequisites" for MCM such as NVSE installed. The install script checks for them. Install manually. You might find this "security issue" is related to something else running on your system (such as an anti-virus program), but sometimes a manual installation is the fastest way around the problem (especially if everything else works fine). MCM install is quite straightforward as I recall: just unpack the archive into your "Data" folder. As you use NMM, check it's documentation to see if it has a specific folder (something like "Overwrite") where are you supposed to place such "manual" install files. -Dubious- Link to comment Share on other sites More sharing options...
