I'm using Magento Community on my Win8.1 with Apache2.
I've been using Magento Connect Manager install a lot of plugins.
I'm trying to install M2E Pro today and I got a problem, which is the error below:
" Checking dependencies of packages Starting to download m2epro_ebay_magento-6.2.1.tgz ... ...done: 2,347,484 bytes Installing package community/m2epro_ebay_magento 6.2.1
CONNECT ERROR: Failed to open file C:/Program Files (x86)/Zend/Apache2/htdocs/magento\downloader.cache\community\m2epro_ebay_magento-6.2.1\app/code/community/Ess/M2ePro/Block/Adminhtml/Wizard/InstallationEbay/Installation/ModeConfirmation/"
I think the reason is that some settings on my machine cutted off the path of the file...I had a similar problem before, same case: path was too long.
Update:
I don't think its permission problem since I installed other plugin successfully before.
