ArcExplorer not launching

[FrostyFirestar2099]

Was using it last night just fine, but when I woke up it randomly refused to launch. Deleted it and redownloaded it, and the issue is persisting. Any ideas as to what I could do to fix this?

Can you upload the log.txt? If you're on windows, you can type %localappdata%\ArcExplorer into the address bar in file explorer to open the right folder.

Yes, here it is:

There don't seem to be any issues in the log. Do you get any error when launching ArcExplorer.exe from cmd.exe or windows terminal?

[FrostyFirestar2099]

I do not know how to do that, but I will try it if you can give me the command

[ScanMountGoat]

If you open the folder with arcexplorer in it and type cmd in the address bar, it should open a new window. Type ArcExplorer.exe and hit enter. If you can take a screenshot of the error, that would be helpful.

[FrostyFirestar2099]

[FrostyFirestar2099]

Nothing. It shows up in my task bar and then disappears

[ScanMountGoat]

Thanks for testing that. If it's not giving any errors, it's unlikely to be something I can fix on my end. There are a lot of issues that can cause a program to not launch like antivirus software, conflicts with other programs, etc. I'll leave this issue open for now in case anyone has a similar problem.

[FrostyFirestar2099]

Alright. Thanks for your time

[touyahoko]

Hello, I can't load Data.arc in ARCExplorer and it seems like an error has occurred. How can I open it? Please let me know. Thank you.
