@switt, you might want to look at the DIM filter field in the upper right corner. For example, you can type “bryce” into the field, and see only products with “Bryce” in the title. That doesn’t mean you will get all of them of course, however this is a super-quick way to at least locate some of them. I don’t recall if there’s a way to identify Bryce products without Bryce in the name here instead.
Also, in the “Ready to Download” tab you can click on the “Download Filters” field then temporarily uncheck everything except Bryce, to see only Bryce downloads, although of course they have to be not yet downloaded, so unless you want to delete and redownload everything that won’t work, but if you ever need to start fresh, you could try it out at that point to identify the Bryce stuff separately first.
I found it does go reasonably quickly if I look at the DIM at the items that were not installed and then look for them in the product list. It is still inconvenient (and since I also have a bunch of Carrara items,as well I still need to determine which is which). But at least this way it is only inconvenient not impossible LOL. I think by now I found most of my Bryce stuff again… and installing them manually shouldn’t take too long now either.
Thanks again for the advice everyone.
