Summary	0031167: Steam: Third-party "Steamworks_gml" extension no longer works for VM, only YYC
Description	We now have a couple of reports asking why a third-party "Steamworks_gml" extension no longer works for Windows VM, only YYC. This looks like a 1.4 extension which is still in popular use today. Currently, the belief is that the VM runner is linked using a different version of VC++ runtime to what the dll is expecting, whereas YYC will link it using whichever VC++ runtime is on the dev's machine during the build process. The source for this extension can also be found at https://github.com/Stormchaser2018/steamworks.gml
Steps To Reproduce	1. Make sure you have the Steamworks SDK installed, etc. 2. Run the attached project for Windows VM 3. You will see in-game text that the extension failed to load and in your output window you will have the line "LoadLibraryA failed with error code 127". 4. Run it for YYC instead and observe all works. Repro: 100%

YYC is also failing on my setup so I suspect an issue with the actual DLL

Dan 2019-08-16 15:06 Adminstrator ~0064566	Closing as per the above comment. Note also that we have made a change for 2.2.4 which will ensure that the correct Steamworks dll is being used on VM, which may also fix this if it was on us.

~~YellowAfterlife~~ 2019-08-16 15:12 Viewer ~0064567	Indeed, that was due to https://bugs.yoyogames.com/view.php?id=31203 - while the original build of the extension used 1.35a (and continued to function as normal), issue author compiled it against 1.42 (as GMS2 doc suggested), which broke because VM would use 1.35a instead of the DLL from specified SDK.
