I am not sure if SHLWAPI.DLL:StrNCatA is a Win95 file or part of UAE.
If it is a Win95 file then you should be able to get it from a Win95 install CD. There may be other files missing.
Many systems did not have the full install of Windows(any version) especially if set up by a company or school IT department. Such administrators typically install only what they wish the user to be able to access. Many companies stripped out internet ,games,tools,and even backup functions.
Some suggest older versions of UAE or Fellow for older PCs.
