TYPO3 v9.5: installation error Uncaught RuntimeException

Question

I have unzipped the installation folder. When going to the install.php to start the installer I get an Fatal error: Uncaught RuntimeException.

I use XAMPP with PHP 7.2 and I go to: http://localhost/typo3/install.php

I get following message:

Fatal error: Uncaught RuntimeException: Could not create directory "/Applications/XAMPP/xamppfiles/htdocs/typo3temp/var/log/"! in /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Utility/GeneralUtility.php:2172 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Utility/GeneralUtility.php(2140): TYPO3\CMS\Core\Utility\GeneralUtility::createDirectoryPath('/Applications/X...') #1 /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Log/Writer/FileWriter.php(222): TYPO3\CMS\Core\Utility\GeneralUtility::mkdir_deep('/Applications/X...') #2 /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Log/Writer/FileWriter.php(193): TYPO3\CMS\Core\Log\Writer\FileWriter->createLogFile() #3 /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Log/Writer/FileWriter.php(123): TYPO3\CMS\Core\Log\Writer\FileWriter->openLogFile() #4 /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Log/Writer/Fil in /Applications/XAMPP/xamppfiles/htdocs/typo3_src/typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 2172

The error means that php cannot write to your xampp htdocs directory, because of security restrictions of the Applications dir. You should change your xampp configuration like in this tutorial https://pureinfotech.com/install-xampp-windows-10/
