I am a current user of LR 5 and I am happy with it. But I just purchased a Canon 5DSR and as you know LR 5 will not read its raw files without converting them. I managed to pick up a license for LR 6. My question is can I run both versions on same PC without conflict? I would have no problem using LR 5 for my "old" pictures and LR 6 for my "new" Canon 5DSR pictures if I could.
