how to install file packages in magento 1.5

I'm using magento 1.5. I have a requirement to install a third-party ecommerce package. Wh开发者_JAVA技巧en i log into Magento Connect, i do not see "Direct package file upload" as an option.

In 1.5 how do i upload a zip/tgz etc?

i don't know why the "direct package file upload" doesn't show up (maybe a permission issue?) but you can manually upload the files/folders where they belong.
At the very least you'll have one folder to put into app/code/community/ and one file into app/etc/modules/. And maybe something in app/design/frontend/base/default/, lib/ and skin/.
If you list the contain of the extension I'll be able to help you more precisely.

I upgraded to 1.5.1 and the "direct package file upload" appeared.
