I just updated both VSTsound files that Download Assistant offered in Update section - Hypnotic Dance and Triebwerk updates. I did it by clicking “Install all” (maybe this causes the problem?). After successful download and installation DA deleted downloaded files. I click “Install again” on both, but one by one and DA leaves downloaded files. Didn’t try to click “Install all” for second time.
had the same just today with updated for TGuitar and Transverse. But it seems to be on purpose just for small updates. And I think it makes sense.
Because I noticed when you download any full installer, it will not be deleted. As it should be. (Downloaded full TGuitar, Transverse and Cubase 12.0.20 Pro)
