Just put together my new computer,,oops no disk drive, how do I get my new lightroom cd, or product into the computer?
You can copy the install files to a USB drive on a computer which does have an optical drive. You can then use that USB drive to install Photoshop Lightroom. Alternately you may also want to look at obtaining a USB optical drive to help resolve these type of difficulties in the future.
Alternately you can download Lightroom 4.4 from the update page applicable to your operating system.
