Leawo's PhotoIns has 3 modules -- this GOTD offer is a 1 year license for the Enlarger, with the other 2 modules working as trials. It requires a bit of disk space with the program's folder taking up 2.32GB. You'll also want a graphics card rather than a GPU that's part of the CPU for best performance, though the latter may still work -- almost all processing was done on the GPU in testing. The Enlarger module does allow for some adjustment or enhancement -- I bumped up the Denoise and Deblur, and the effect, while slight, was noticeable IMHO. That said, the result couldn't compare to a copy of the same photo, a 35mm negative scan, that had been edited in Photoshop and using Luminar Neo. But, the module's true purpose is to enlarge photos, and that it did well, with no noticeable difference between the original and the new copy at twice the size. Until you activate one of the modules PhotoIns shows a registration window when you start the app -- copy/pasting the key and clicking the button activates the Enlarging module. Afterward there's a button that looks like a key in the upper right of the main window -- clicking it brings up that registration window. Clicking the Enlargement module opens the enlarger in a separate window. While it says it supports drag/drop, that did not work with a .tif file.
Today's GOTD is a downloader, with the true setup file taking up ~1GB -- it was saved in the download folder after installation. Additional folders are added to ProgramData & Users\ [UserName]\ AppData\ Roaming\ and Local\. Empty folders for all 3 modules are added to Pictures. The registry gets 2 keys for the app itself, one for uninstall, and a Phymem2 service. I was a little leery of that service since Microsoft's tightening up on 3rd party drivers and such, so I performed my testing using a copy of Win11 24H2, which is said to be stricter in that regard, and didn't see any problems.
