Hi! I'm currently want to try to use Magento Community 2.1.5. Running Windows 10 and IIS using PHP 7.0.16. However although I installed, I keep getting same error. It is written as below in 'var/log/system.log' file.
[2017-03-15 07:29:45] main.ERROR: Sample Data error: The path ".://C:/Windows/Temp/C:/Windows/Temp/" is not writable  
Here indicating sample data is trying to write to the directory '.://C:/Windows/Temp/C:/Windows/Temp/' rather than 'C:/Windows/Temp/'.
Please do note that, I do know how to convert .htaccess to web.config, and set permission for IIS_IUSRS on all folders including 'C:/Windows/Temp/'. And I doubt it has anything to do with those.
Magento doesn't support IIS officially. It supports Apache and NGINX.
I am using 2.1.5 with Xampp in Windows 10. It works perfectly, with and without Composer.
Better than on the remote server as I described elsewhere.
Exactly. Xammp is using apache behind, and that's why it's working good for you.
Thanks for the information! Unfortunately, it is also a bad news for me/us as we required to run on IIS and came across this:
However, it contains error while installing sample data. And after your message I tried it on the one without sample data. It was successfully installed but can't get it to display static contents such as CSS and JS even used the 'setup:static-content:deply'.
Was originally intended to look for workaround for running on IIS server because of production hosting is a Windows reseller hosting
Thanks for your message and information. Actually I do know about Xampp and Wamp as I used it few years ago. Right now I'm .NET developer, so would rather to run PHP on IIS. And also because of the production hosting is on a Windows reseller hosting, I can't use Xampp and Wamp for testing as well.
