Reinstall adobe photoshop lightroom

I purchased the CD several years ago and have used all of my key codes.

Which version exactly? What do you mean by all of my keycodes? Do you mean activations?

Software back then was sold with a single 24 digit serial number which you need to use every time you reinstall it.

You may be able to find your serial number by signing in your Adobe account

Also, which operating system are you running?

A disk version of Lightroom is ancient, out of date, and completely unsupported by Adobe. It won't be possible to obtain a serial number from Adobe because serial numbers are not used anymore. The replacement for what you used would be Lightroom Classic which is available by subscription only. The photography plan, which includes Lightroom Classic and Photoshop is available for $9.99/month in the US. There have been countless new features added to Lightroom over the years since the old standalone days. If you cannot locate your serial number, the first four digits being 1160, I don't know of any way for you to install your old version.
