Error in all logs reads: The lz4 assembly requires the Microsoft Visual C++ 2015 runtime installedlz4.AnyCPU.loader When I try to install 2015 version I get the error message that I have another version of the program installed. https://i.imgur.com/PTGxIqx.jpg Do I need to uninstall some of these versions for the 2015 version? edit: Ahh I am seeing another user sam_dmitry had the same issue and your advice was to install the runtimes/obtain a legal version. My version is legal and I have the runtimes. I'll uninstall the x86 versions as it sounds like sam_dmitry did and report back on this. Thanks. edit2: if it matters I have the game, DynDOLOD, and the runtimes all on 3 separate HDs. Runtimes are on OS SSD, DynDOLOD is on storage HDD, and the game is on SSD for games.
