How can NSIS verify the DLL? How can an installer from, say, 2012 know if the copy of shfolder.dll in Windows 10 is valid?<p>And worse - in some cases, NSIS wasn&#x27;t even directly loading the DLLs, Windows was doing it behind its back (eg. NSIS called a Win32 function called OleInitialize, which loaded UXTheme.dll by itself).
