Hello,

When I try to use steam in my project and launch it, I get the following error (with 4.6):

I copied all the dlls as stated in the wiki and the docs.

How can I fix this?

Ok the github version works. Still would like to fix this.

Were you logged into steam at the time?

I’m also having this issue. Did you ever fix it?

Sorry to necro this thread but ran into a similar issue and was able to fix it by dropping a steam_appid.txt next to my executable with the AppID in it so the API would properly initialize in Developer builds I was trying to launch. Sourced the solution from here:Steam Docs
