I can't reproduce that issue.

For me everything works fine after the latest updates (RC + Dev).

Do you use any mods or have you modified your game location?

I've been on dev branch for a while since I'm working on a few EDEN Editor plugins, but since I downloaded the ~150MB update today the launcher is outright broken.

I can't start the launcher in any way, tried using the safemode parameter. I tried deleting the config in appdata and I have also deleted ArmA 3 from Steam and manually deleted all my addons and downloaded it all over - same issue persists.

I would try some more things but jumping between stable and dev branch takes quite some time.

I can launch ArmA 3 via the arma3.exe, it's the launcher that's having issues. If I try and play via Steam, Steam thinks the process is running and I can only fix it via a hard reboot.

I have absolutely no clue why this started happening, it was working fine just before that update.

Edit:

It might be worth mentioning that I have also deleted the launcher config in my local appdata folder to no avail.

Stable or dev branch, launcher works for neither. Not even after a full re-install.

Any suggestions to further troubleshoot this would be appreciated.

I was experiencing this problem yesterday; I'll look into it

Hmm, I tried it just now and it seems that the launcher there is a delay between hitting the play button on the launcher and the actual game loading up.

My issue though is that the Launcher doesn't run at all. It's as if it doesn't even execute, see this GIF for example;

Hello,
could you please check your desktop for text files with error report and upload them?

For some reason it seems as if the launcher is working today, I've absolutely no idea what's going on.

I left my computer on over night, and now the launcher is working. Was there some update during last night?

Edit:

I don't have any report files, neither on my desktop or in the typical profile folder where they are to be found.

Hello Dealman,
thank you for response. Could you please open Windows Event Viewer, navigate to Windows Logs / Application log and look for any error that occured at the time you unsuccessfully attempted to start Launcher yesterday? There might be an error record, it would help us if could save those records - if there are any - and upload them here.

I took a look at the Event Viewer but I can't find any traces of the launcher, only for when Steam hang and when I tried to run ArmA 3 Diag but it crashed as well.

Would these be of any help...?

Edit:

Welp I take that back. Since it was again working I decided to go back to the dev branch in hopes to continue working on my mod.

However, now it's broken again. Trying to start it in Steam causes Steam to hang and I have to kill the process. If I restart Steam, Steam will automatically assume that it's still running.

If I try and execute the launcher via explorer, my cursor gets the loading state stuck until I have rebooted my computer.

This is after having completely deleted and re-installed ArmA 3 via Steam.

Edit:

Did some more testing;

1. I reverted back to stable branch and closed Steam once done.
2. I tried to start ArmA 3 Launcher manually - it works.
3. I start Steam and try and play via Steam - it works.
4. I exit the game and update to the dev branch.
5. Again, I close Steam and try and run the launcher - it does not work.
6. I try and run ArmA3.exe - does not work.
7. I start Steam and try and run it via Steam - it hangs and eventually crashes - a reboot is required to fix Steam.

I have no mods and I have deleted my ArmA 3 profiles, so it is most definitely something with this version of the dev branch that does not work on my system.

I have uploaded a fresh copy of my DxDiag in case that is of any help. I really hope we can sort this out. :(

Still having issues with this... It was working for a while but now it's broken again, I'm starting to suspect that the issue lies within the AddonBuilder, for some reason it messes something up which makes the ArmA 3 launcher unable to run.

Yet again, I can't start ArmA 3 whatsoever. Was working fine yesterday, haven't touched it since.

Edit:

I saved some of the Events starting when Steam freezes, in case it might be helpful. Since the format isn't allowed here, I've uploaded it to MediaFire;
