Is there a way of buying the new Lightroom CC without taking the monthly plan option? I cannot seem to find it on the Adobe Website, if possible can somebody please forward the link or the where to find this?
No there isn't. Lightroom CC needs the online CC storage to store the original images, so it wouldn't make much sense either.
The last of the Lightroom desktop applications available is Lightroom 6.14 and this was released towards the end of Dec 2017.
I believe it is still available for purchase and you can try the link below to access it.
You may have to type Lightroom 6.14 in the search box, near the top of the page.
As indicated above it is the last available version and there will be no further updates. It should continue to function as long as your hardware and operating system continues to support it.
