Unable to load native DLL.

Question

We have a problem with a third party native code dll:
Unable to load DLL 'ThirdParty.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E).
It looks like that some dependencies are missing.

We do have a workaround. It could be loaded successfully if we compile it with some project settings change:
1. Change the property “Runtime Library” from “Multi-threaded DLL(/MD)” to “Multi-threaded(/MT)
2. Add msvcrt.lib to “Ignore Specific Default Libraries” property
The problem is that the source code usually comes with a long delay so we would like to find a possibility to use binaries.
Any suggestions?
Thank you.

Answer 1

What specific DLL are you using, it may be obsolete and need replacement, likely it was make with an earlier SKU of Visual Studio

the general way to call a library is with LoadLibrary()

eg

LoadLibrary('ThirdParty.dll');

however if you are experiencing problems, you may need to find a new version that is designed for your SKU of Visual Studio

Answer 2

Use Dependecywalker tool or Process Expolrer to find out which dependent dll is not present on your machine, it looks like you have some runtime dependecy

use the /MD switch and install the correct Runtime and your issue should be resolved
