Hello folks,

revisiting, still present.

x64dbg requires Concurrency Runtime scheduler API to asynchronously execute
commands ('DbgCmdExec', '_dbg_dbgcmdexec').

It makes use of asynchronous message blocks, implemented using concurrency API.

The concept is described here: 

https://docs.microsoft.com/en-us/cpp/parallel/concrt/asynchronous-agents-library?view=vs-2019
("Asynchronous Agents Library")

https://docs.microsoft.com/en-us/cpp/parallel/concrt/asynchronous-message-blocks?view=vs-2019
("Asynchronous Message Blocks")

https://github.com/x64dbg/x64dbg/blob/58825d4522f06986e09ab17b141204a66e68dd15/src/dbg/msgqueue.h

https://github.com/x64dbg/x64dbg/blob/58825d4522f06986e09ab17b141204a66e68dd15/src/dbg/msgqueue.cpp

BTW there is no need to pollute the WINEPREFIX globally with VC++ 2013 runtime
using 'winetricks'. It's rather harmful, especially if you want to debug bugs
that are in same component(s). x64dbg ships the VC++ 2013 runtime in the app
folder:

Hence just make an app-local registry override or use:

$ WINEDLLOVERRIDES=msvcr120,msvcp120=n,b wine ./x32dbg.exe
