If I understand correctly, this is on Debian 11 a.k.a. Bullseye. This is the current "oldoldstable" release. You should upgrade your OS to the current stable version.

The key is 2.31 here, too old. LDD checks for 2.32 and higher.

On Atomic Fedora, all end in computation error as well thanks to the libzip4;
error while loading shared libraries: libzip.so.4: cannot open shared object file: No such file or directory

Thought it was memory related as only have 8 GB but this does not seem the case.
I might give it a reboot when I get round to it, stopped work fetch for the time being

"LODA v2601.25 windows_x86_64" version of the app still generates the error: "The operating system cannot run (null)."
Only "good" thing is that the tasks take a few seconds to fail.

To all Windows users, follow the instructions in the following post to resolve the problem.

https://boinc.loda-lang.org/loda/forum_thread.php?id=136&postid=1050#1050

Perhaps it could also provide useful guidance to other users with operating systems different from Windows.[/url]

Message 1061 - Posted: 16 Feb 2026, 17:35:56 UTC - in response to Message 1057.  

Before trying version 260214, I disconnected and then reconnected the project to have a clean setup, to avoid anything old interfering with the test, and I must say it works excellently.
At the moment, I have a completed and returned wu without errors and two others that are processing.
Well done, it seems that the problem has been resolved on the Windows platform.
