ive made some changes & now BOINC will not run.. Ive uninstalled / installed BOINC & now get

Message:- Windows 11: windows cannot find C:\Program Files\BOINC\boincsvcctrl.exe

I cannot add or find any projects (the option is there but not active / available)

Ive downloaded / uninstalled / installed / uninstalled / installed the latest version of BOINC: for Windows intel-compatable 64-bit.

any idea how / where i can get the boincsvcctrl file ?

EDIT: Windows 11, BOINC MANAGER version: 8.2.11 (x64), wxWidgets Version 3.3.1

What AV programme are you running? It might have taken exception to that file and is killing it each time you re-install BOINC.

Unless you've installed another one, that would be it.

I'd suggest going in to it's Settings (Windows Security, Virus and Threat protection, Virus and Threat Protection Settings, and right down the bottom of that page is Exclusions, Add or remove exclusions.
Add an exclusion).
In there, add
C:\ Program files\BOINC
and
C:\ ProgramData\BOINC

a third party programme will have a similar option.

Once that's done, try installing BOINC again.
If it's still giving issues, re-boot the system, Use Windows Explorer and delete C:\ Program files\BOINC, then re-install BOINC.


At the very bottom of Windows Security is Protection History- select that and see if there is anything mentioned there in relation to BOINC.

This file is installed when BOINC is set to be installed with the 'Service Install' type.

FIXED:-

I didnt find any documentation pointing me to it, but I was just browsing the settings & found the FILE >> SELECT COMPUTER.

this was blank, so i googled that, & it told me to put 'localhost' etc.

Now all my tasks are appearing...
