**My software**  
My Mautic version is: mautic-5.1  
My PHP version is: php-8.2.27-nts-Win32-vs16-x64  
My Database type and version is: 8.0.30  
WebServer: Laragon

**My problem**  
My problem is: When I try to install mautic via composer the following messages appear for the composer update and composer install commands

These errors are showing in the log:

_PS D:\laragon\www\mautic-5.1\> composer update_  
_Loading composer repositories with package information_  
_Updating dependencies_  
_Your requirements could not be resolved to an installable set of packages._

- Problem 1\*
- 
  - Root composer.json requires mautic/core-lib ^5.0 → satisfiable by mautic/core-lib[5.0.0-dev].\*

- 
  - mautic/core-lib 5.0.0-dev requires ext-imap \* → it is missing from your system. Install or enable PHP’s imap extension.\*

_To enable extensions, verify that they are enabled in your .ini files:_

- 
  - D:\laragon\bin\php\php-8.2.27-nts-Win32-vs16-x64\php.ini\*  
_You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode._  
_Alternatively, you can run Composer with `--ignore-platform-req=ext-imap` to temporarily ignore these required extensions._

**My problem 2**

Quando tento acessar o site pelo localhost, demora muito para carregar a página de instalação e quando carrega a tela fica presa na primeira tela

These errors are showing in the log:

Steps I have tried to fix the problem:

I tried installing several versions of mautic from 3.0 to 6, changing php from 7.1 to 8.3 and I was unable to install any of the versions.
