TerryfromtheToon Posted 3 hours ago Share Posted 3 hours ago Fallout 4 will open the Launcher, but when pressing 'Play' Steam sends a notice that the application is attempting to launch with the '-len' argument, and gives the option to Continue or Cancel. Same thing happens with F4SE. I have 840 hours in the game and this has just started happening. I have un-installed, re-installed. Changed program parameters in Windows to launch as Administrator and run in Windows 7 compatibility mode. I have deleted all INI files and let Steam repair the program. I have tried putting my own arguments in Steam to run with this program. Oh and -len=false doesn't work either' I cannot figure out why this is happening or how to fix it. There are only a few threads out in the wild with this same issue. All of the suggestions in those threads have not worked, and I'm not sure if the OP of those threads ever got their game working. Purging mods doesn't make any difference. The only wayI can get FO4 working is to uninsall then delete the FO4 folder completely then reinstall. Then I can play vanilla (no thanks). As soon as I try with F4SE it crashes again. Frankly i'm stumped and any help would be great. Is there anyone familiar with this issue, know what causes it, and how to fix it?

HeyYou Posted 3 hours ago Share Posted 3 hours ago Ok, that's a command line switch that limits the character length of the command line. Which seems a little odd to me..... Unless it is set to something truly short, continue should work just fine.... If you ONLY see that launching with F4SE, I would re-download it, and try a reinstall.

subaverage Posted 2 hours ago Share Posted 2 hours ago Is it possible that the argument is set in Steam itself? You look in Steam into the properties of your Fallout 4 and under general (I hope these are the correct english expressions). The last point should be something like "start options". You could check whether there is an entry in this field. Link to comment Share on other sites More sharing options...
TerryfromtheToon Posted 53 minutes ago Author Share Posted 53 minutes ago @subaverage, no, this is where I tried the -len=false command, it didn't work. Link to comment Share on other sites More sharing options...
TerryfromtheToon Posted 52 minutes ago Author Share Posted 52 minutes ago @HeyYou, strangely this is the only thing I haven't tried, gonna give it a shot in the morning and will report back. Link to comment Share on other sites More sharing options...
subaverage Posted 31 minutes ago Share Posted 31 minutes ago Good luck, but one question though. Is Fallout 4 your only Steam game affected by this error? If not, the problem might not be Fallout. Link to comment Share on other sites More sharing options...
TerryfromtheToon Posted 9 minutes ago Author Share Posted 9 minutes ago @subaverage, the only game. I think it's solved though due to HeyYou's post. Thanks for looking. Can't believe it was somrthing so simple. Link to comment Share on other sites More sharing options...
TerryfromtheToon Posted 6 minutes ago Author Share Posted 6 minutes ago @HeyYou, you sir are a genius. I've tried for two days to solve this to no avail. Redownloaded F4SE and installed alongside half a dozen mods and it now runs flawlessly. Can't believe I didn't try this earlier. Thank you so much for your help!
