I trying to install CiviCRM 4.7.14 for wordpress 4.7 on windows machine, all steps of installation based on official CiviCRM installation guide. After step where i setup database connection and click install i got at left panel icon civicrm how it must be, but after click on this button I got error about non correct path in civicrm.settings.php, after fixing double slashes to single slashes “/” in this file and update page I got next error that I can’t solve

Fatal error: Uncaught CRM_Core_Exception: [0: Found installation canary. This suggests that something went wrong with tracking installation process. Please post to forum or JIRA. thrown in C:\xampp\htdocs\wp-content\plugins\civicrm\civicrm\Civi\Core\InstallationCanary.php on line 53

All requirements are fine and I do not got any warning or errors at step with install.

I just did an installation on my Windows Laptop, and it worked. I describe below my configuration. Maybe it leads to a working configuration on your system.

1. I downloaded and installed the xampp-win32-5.6.28-0-VC11-installer installer from ApacheFriends. The installation decides for the default home C:\xampp.
2. After the installation, the Xampp control panel starts. I start Apache and MySQL.

3. I open the shell to create the databases (I am more at my ease with Unix). I create the databases with the following commands:

   mysql -u root
   
   create database wp character set utf8;
   create database civi character set utf8;
   grant all on wp.* to wpuser@localhost identified by 'wppwd';
   grant all on civi.* to civiuser@localhost identified by 'civipwd';
   flush privileges;
   

4. I install WordPress by unzipping the download in the C:\xampp\htdocs directory. I remove all other files (to keep the installation clean).

5. I do the WordPress configuration according to the documentation. (database wp, user wpuser, password wppassword).

6. I unzip the CiviCRM (civicrm-4.7.14-wordpress.zip) in the directory C:\xampp\htdocs\wp-content\plugins.

7. Now I activate the CiviCRM in the plugins menu and complete the installation with the Almost Ready invitation. (database civi, user civiuser, password civipwd).

8. Installation completes without problems.

The civicrm.settings.php file is generated in the directory C:\xampp\htdocs\wp-content\uploads\civicrm. In the file is a mix of forward slashes and backslashes, but CiviCRM does not seem to bother. For example:

$civicrm_root = 'C:\\xampp\\htdocs/wp-content/plugins\\civicrm\\civicrm\\';
if (!defined('CIVICRM_TEMPLATE_COMPILEDIR')) {
 define( 'CIVICRM_TEMPLATE_COMPILEDIR', 'C:\\xampp\\htdocs/wp-content/uploads\\civicrm\\templates_c\\');
}
