The PCs I intend to use this on have fully encrypted hard drives. Guess I'm confused here. I mount the WIM for my existing WinPE, then copy the files I extract from the ERD tools.cab and place them into the appropriate folder (they all seem to belong in system32 with maybe 1 or 2 exceptions), then remount the WIM and boot into WinPE. I have A43 starting (that's how the WinPE is already configured), navigate to the exe for MSDaRT, and it opens fine. I can launch the tools, but most of them do not complete their intended functions. My primary goal is the system restore functionality, but SFC and some of the other stuff would be nice too. If I take another approach, which is to mount my existing WIM, then copy the Windows folder (and all files/subfolders) that i extracted from the ERD initially, then the following happens: A43 file manager is no longer launched automatically; instead the first thing that comes up is the RECENV.exe system recovery screen, which then triggers startrep.exe, and from there I select the OS, etc etc, and can get MSDaRT that way. i can actually launch Explorer then navigate to A43 and open it, and see all of the options I've customized for it, including the built-in tools that the encryption software vendor included to bypass the encryption and interact with the encrypted hard drive. Unfortunately the tool that bypasses encryption (provided by vendor) seems to work but fails at the very end because some files or filters aren't in place (having been displaced when I simply copied the Windows\*.* folders from the ERD into my existing WinPE). Since System Restore works when I copy the entire Windows folder from ERD into my WinPE, but fails instantly if I only copy the files from the tools.cab, I would pose the argument that more files are needed than simply what exists there. Not trying to be a d*ck I absolutely appreciate any input at all, and there's a chance i'm just going about this the wrong way, but I do have some limitations because of the encryption filters and utilities that are incorporated into the existing WinPE. And which files they use, and how they're loaded... i have no idea, and the vendor is less than helpful, so I'm stuck groping in the dark a bit.
