Something went wrong while installing sample data. Please check var/log/system.log for details during Magento installation

Question

I am a beginner in Magento. When i was trying to install "Magento-CE-2.0.0+Samples-2015-11-17-06-11-18.zip" on my local server using Wamp,it first gets stuck at 90%, after quite a while, it shows "Success" but at the end of the page it shows the following error-

"Something went wrong while installing sample data. Please check var/log/system.log for details. You can retry installing the data now or just start using Magento"

I checked the "var/log/system.log" and there is this message-

[2015-12-21 09:42:48] main.ERROR: Sample Data error: Warning: IntlDateFormatter::parse(): Date parsing failed in C:\wamp\www\Magento\vendor\magento\framework\Stdlib\DateTime\Timezone.php on line 166 [] []

when i click at the button "Launch Magento Admin" which is situated at the bottom of the page, i get this error

What can i do to solve this problem?

I have already posted it on "Stack Overflow" because i didn't know this forum exists. There is no answer on "Stack Overflow" so i have posted it here again.

Answer 1

I could not find a solution for date parsing issue yet. But as per sample data installing you can try below commands from your installation directory.

php bin/magento sampledata:deploy
php bin/magento setup:upgrade

then compile if required

php bin/magento setup:di:compile

Answer 2

Many people are facing different problems while installing Magento 2 with sample data. I would suggest try installing Magento without sample data and see if error exists.

Before beginning, make sure you have these on-hand for Magento 2 installation because this may cause an error as well:

Apache Version 2.2 or 2.4, PHP Version 5.5.x or 5.6.x & MySQL Version 5.6x.
