Hello guys, since the bug thread is closed I thought I'd create a new thread about some minor issue I'm having. I'm trying to install the 4.4.0 version of AB over my current beta installation. Everything goes ok but for one file: 'RTCore64.sys' The AB installer gives me an error saying that he can't access or modify the file, and give me the three classical options 'abort', 'retry' and 'fail'. If I choose to ignore the file, the installation proceeds smoothly, and I can continue to use AB ok, but I'm wondering if I'm missing some new feature by not changing this particular file. Ah, and before someone asks, I really don't like fresh installs because it's a PITA to reorganize my OSD options again. I really wish unwinder implemented some way of exporting this settings... Thanks. EDIT: I'm running Win10 x64 FCU always updated.
