Portable LocalSend executable: Can’t access file or insufficient permissions

The portable version of LocalSend is supposed to allow for its use without installation and without administrator rights.

I obtained the zip filel from the LocalSend page.

When I use my non-administrator account to double-click “localsend_app.exe”, I get the message “Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item”.

The file is located on the C-drive, an NTFS HDD, in an folder to which my non-administrator account has full access. I am running Windows 11 Pro, updated 5 hours ago. As screen-captured below, I tried to view the permissions of the file, but I see no Security tab in the Properties panel: Neither is there an “Unblock” option in the file’s context menu. I ran sfc /scannow but it didn’t help. The resulting output message was:

Windows Resource Protection found corrupt files and successfully repaired them. For online repairs, details are included in the CBS log file located at windirLogsCBSCBS.log. For example C:WindowsLogsCBSCBS.log. For offline repairs, details are included in the log file provided by the /OFFLOGFILE flag.

As per this Microsoft page on system file checker, I am currently running DISM.exe /Online /Cleanup-image /Restorehealth. Since I never have such problems running exe files, however, I am not hopeful that it will point to a solution.

Based on the comments, I realized that I was unused to seeing Windows’s double row of File Properties tabs and completely missed the Security tab. Descending into it showed that I do not have execute permissions, I am always confused by Windows’s security checkboxes, so I used Cygwin’s Bash to grant execute permission to myself: chmod u+x localsend_app.exe. This seemed to enable the proper checkboxes:

However, the application is now unable to start properly:

Thanks for any suggestions.
