I'm attempting to create Windows 10 Repair usb & need to do so in Ubuntu - my laptop is extremely boorish & sluggish to the point it barely boots into Windows so thats not an option.

After issuing wine upgrade.exe, I'm told the mfc42u.dll library is missing. Upon inspection, it is there.

I've tried unregistering & reregistering the dll in both system32 & syswow64. I've also tried physically placing the dll inside the directory I'm trying to run the program with. All options have failed. Idk if it has anything to do with the program itself or if there's a deeper cause
