Hello,
could you please install these packages? They were supposed to be installed automatically by Steam but for some reason that might not have happened:

and also

If you have x64 system:

If you have x32 system:

Could you please also upload your launcher logs? You can find them here:
C:\Users\[username]\AppData\Local\Arma 3 Launcher\Logs\

Thank you very much.

The new updated launcher is still doing the same thing. Its telling me to make sure the client is running, which it is. Anyways, I uploaded both .rpt files in the \logs directory.

Also, forgot to add, all the links you sent have already been installed by Steam, so those ARE there. Just for some reason, which I'm sure the logs may explain, it won't see the Steam service and stay open.

Hello,

thank you for uploading logs. We're currently investigating your problem. I would like to ask you to switch to a development version, if you can, and run the Launcher. Is that possible for you?

Also I would like to know:

• Do you have UAC (User Account Control) enabled on your computer?
• Are you administrator on your computer?
• Do you run the Steam or the ARMA as administrator?
• Are you participating in the Steam Beta?

If UAC is referring to the window asking for an admin password, then yes. I was not admin on the PC that is having problem now. But I WAS admin on the PC that is working properly now. Steam is not set as admin on PC with problem, nor arma. I am not in steam beta. My internet speed was recently increased on the download side, so I can most certainly try the dev build on PC having issue.

Also, thanks so much for the help. Really appreciate it.

Hi,

thank you for you patience. We're currently investigating the possibility, that the Launcher and the Steam are isolated from each other by operating system. It could be connected to the fact you're not an administrator.

I'd like to ask you do following on the computer where you're having problem (where you're not the administrator):

1. Run the Launcher.
2. Run the Steam.
3. Open Command prompt.
4. Type and run following command: tasklist /V > willymattash_tasklist.txt
5. That command should create willymattash_tasklist.txt in your profile folder. That file contains a list of processes running on your computer.
6. Please upload the file here (if you couln't find the file, type 'start .' in the Command Prompt).

Closing because Launcher's architecture and communication with Steam client is now different and there was no activity on this ticket for 3 months.

Please feel free to create new ticket if problem still occurs.

i am facing the same problem, with the launcher saying steam is offline when its is not. Also I am the admin of the pc and run steam as administrator and have steam beta update participation.
