Build/running difficulties

Running this with the latest x86 visual studio redistributables:

Results in the following error code:
CreateFiles failed with error 2

Wont work with just the x64 redistributables installed, I take it this is a x86 build?

Trying to build this with Visual Studio 2019, gives a bunch of errors centered around 'not able to convert from LPCSTR to LPWCSTR' in the function calls.

Yeah its x86 to run both on Win10x64 and Win10x86.
I assume you build it using Debug compiler mode.
Try to compile it using Release and x86.
It also should compile as x64.

Unfortunately no -
Full error list:

This is the same in release mode for both x86 and x64.
Do you know what the error from the pre-built one you made relates to?

[inamozov]

Do you use Unicode in your project? Try setting multi byte character set

[mattreecebentley]

That makes it build in both x86 and x64 modes, but still get the same error when running.

Idk what you are talking about. Provide more info please or google it.

As I said in the first post:

No different for the rebuilds I've done. Code doesn't work.
