IMAGICK doesn't install in PHP 8.1.12 on Windows 11

[Geoff]

IMAGICK does not show in Apache 2 PHPInfo or run in my php code after copying php_imagick.dll to c:\xampp\php\ext folder and CORE_RI and IM_MOD dlls to C:\xampp\apache\bin folder. Added extension=php_imagic.dll to php.ini
Running Windows 11 and php ver 8.1.12. Downloaded php_imagick3.7 – 8.1 ts-vs 16 - x64.zip. Checked that all 162 downloaded files are unblocked.
I don’t know why the PHP Warning below is trying to find php.imagick.dll instead of php_imagick.dll
Command Prompt replies below:
C:\xampp\php>php -version
PHP Warning: PHP Startup: Unable to load dynamic library 'php.imagick.dll' (tried: C:\xampp\php\ext\php.imagick.dll (The specified module could not be found), C:\xampp\php\ext\php_php.imagick.dll.dll (The specified module could not be found)) in Unknown on line 0

Thank you, Christopher Becker - I copied an existing ";extension" over my imagick extension in php.ini and re-entered "php_imagick.dll". Imagick installed. It appears in PHPinfo and works in my code
