Hello, i am new to IDA (IDA Free 9.2). Decompiling a visual studio 2022 program (C++ V19) for windows x32, mfc140.dll functions are not recognized. I guess that i need a specific signature file. I tried some signatures from github for several Visual Studio versions, but the problem persist. Cannot find a specific signature for mfc140?! Any idea? Wolfgang ---

IDA can find the the matching pdb. ---

For auto naming ordinal-only imports you need `mfc140.idt`, shipped with IDA Home or any IDA Pro.
