If you're not going to have multiple Runtimes, there's only ONE good way to do it. FIRST create a full COPY of the P5 folder, with all interesting files - the whole Runtime, all your texs and the lot - and then install P6 on top of it, in effect upgrading. This allows P6 to overwrite files it needs to update for UI etc. If you do it the other way round, first install a clean P6 and later add P5 files to it, you may inadvertently overwrite a critical P6 file with an older P5 file somewhere in Runtime, for instance. P6 may fall over. Don't ever take that chance. I did it this way now, (the way outlined above) and I also did it last time - from P4 to P5. This way, with a single Runtime, I've never had problems with INJ files not working in P5 etc. :] Fish
