Да, ваши примеры работают. Вот что у меня:
Код:
$tesseract = "C:\scripts\Tesseract\tesseract.exe"
PS C:\temp\ocr20210306092926> $images |ForEach-Object -Parallel {
>> & "$tesseract" ".\$($_.name)" "$($_.basename)" -l rus+eng
>> } -ThrottleLimit $threads
InvalidOperation:
Line |
2 | & "$tesseract" ".\$($_.name)" "$($_.basename)" -l rus+eng
| ~~~~~~~~~~~~
| The expression after '&' in a pipeline element produced an object that was not valid. It must result in a command name, a script block, or a CommandInfo object.

Вместе с тем, объект-то есть.

И если забить путь руками, то всё работает:
