FeResPost assembly should be installed in the global assembly cache. This can be done by copying the “FeResPost.dll” dynamic link library found in “NET” directory to the Global Assembly Cache. This can be done simply by dragging and dropping “FeResPost.dll” into the “C:/Windows/assembly” directory. Note however that:
You may need Administrator privileges to perform the operation.
You have to choose the right version of the .NET assembly. (See above.)
You can also use an assembly without registration. Then, the assembly must be located in the same directory as the one containing the executable.
The advantage of installing FeResPost in the Global Assembly Cache is that this allows to use from a program anywhere without minding where to find it.
