I have accessibility to LR, but my windows dosen't support the latest version of LR. Meanwhile, Adobe does not provide old versions of it, which makes it impossible to download.

My PC lost some files so it can’t update operative system of Windows, even by downloding update assistant from Microsoft. On the other hand, I don’t know how to get the old version.
