Magento Connect closed

After Magento Team made the announcement about Magento Connect closure, the website was eventually closed down on the 15th of September 2017.

It means that Magento Connect can no longer be used to install/upgrade the Module on Magento 1 automatically. Check out other options of the Extension installation/upgrade.

The detailed instructions on how to install/upgrade M2E Pro Extension on Magento 2 can be found here.
