Victim_913 26 Posted April 11 For some reason, out of nowhere, addon builder stopped opening. I use it all the time. But as of today, I click on it, both from a shortcut on my desktop, and from the steam "arma 3 tools" menu. I click on it, the screen appears and closes immediately. It will not open. I verified the integrity of both arma3 and arma 3 tools. Both are completely validated to be correct. But i still can't open it. I tried opening other tools and they seem to work. it's just addonbuilder. Any ideas? edit: I went into the user logs. This is the error message I get: 2024-04-10 15:09:27,942 [FATAL] 1: System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Root element is missing. (C:\Users\GOD\AppData\Local\Bohemia_Interactive\AddonBuilder.exe_Url_5vzzrasdbaz3le10zjluspzaksqkp5mv\1.5.150.952\user.config) ---> System.Xml.XmlException: Root element is missing. In case its related, I also got a message when opening arma3 from Steam. It said my user settings had been corrupted. I had to reselect mods etc. and then that message stopped appearing. I ran the diagnostics in the tools menu and i got a result but i didn't know how to make sense of it. If thats even helpful Share this post Link to post Share on other sites
Victim_913 26 Posted April 11 Just in case anyone else has this problem, I fixed it. In the info i provided, I went to the file : C:\Users\GOD\AppData\Local\Bohemia_Interactive\AddonBuilder.exe_Url_5vzzrasdbaz3le10zjluspzaksqkp5mv\1.5.150.952\user.config I found the file. the user.config file had no content. it was empty in notepad. All previous entries had data. So I deleted the folder: 1.5.150.952 Actually i saved it to a different location just in case i needed it. Then i verified the integrity of the tools AGAIN. it showed 1 file needed to be replaced. It recreated that file. Now it works. In fact, I think the problem occured because i had it open the other day when my video card stopped working.. Being blind, i had shut down my computer wrong. It must have corrupted the file.
