Why do any tasks I run on my PC #30 crash after a few seconds with
Exit status 1 (0x00000001) Unknown error code?

Computer is running Windows BOINC version 7.16.20 under LINUX WINE WINDOWS EMULATOR.

Task 542325

Stderr output

<core_client_version>7.16.20</core_client_version>
<![CDATA[
<message>
Invalid function.
 (0x1) - exit code 1 (0x1)</message>
]]>

I have seen this on several other BOINC projects and never got answers from them...

I'm going to guess that it has something to with what compilers were used to create the executable program.

OK. Done that. Now waiting for tasks t download & run. Will check back to see how it works.

Also try running the native Linux BOINC client instead of the Windows client with the WINE emulator. It's possible that something is not 'translating' properly in the emulator, especially if you have seen the same error in other projects.

Oh well, No luck under WINE after Detach/Reattach.
Will just stop trying to get this project to run under WINE.
Have other projects with Windows exclusive tasks working fine.

I invite you to the project

Get Symmetrical Tuples App

... Could this be the reason?
Can you double check your settings for host 30?

Nothing wrong with that computer. It's primary/BOOT OS is Ubuntu Linux 18.04 LTS and runs BOINC using WINE.

Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, & BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.

I don't have any extra Windows licenses and don't want to waste $$$ acquiring any license for a 2nd handed free computer that didn't have a hard drive when given to me.

It doesn't have Virtual Box installed under WINE since the BOINC projects I run on it don't need it and this project doesn't use it either.

BOINC 7.16.20 is the most recent version that installs and runs without freezes & crashes under WINE. This should not make a difference.

I have WINE configured to simulate "Microsoft Windows 7" [Ultimate N x64 Edition, Service Pack 1, (06.01.7601.00)].

Like I said in previous post there's several other BOINC projects that the Windows apps won't run under WINE on this PC, which is fine by me and not worth time to troubleshoot.
