Error on installing magento extension using Direct package file upload

Question

I try to install Express Checkout | One Step Checkout for Magento Community Edition v1.7.0.2. But it gives error:

CONNECT ERROR: Permission denied to write to var/package/tmp/\K:\xampp\htdocs\trial1\var

Answer 1

I already solved my problem. Instead of using a direct package file upload, I copy the extension to the Magento folder. Log out admin and login again, refresh cache if necessary. But it doesn't display on Magento connect manager.
