If some games are copied directly, there will be problems in operation, but glory usually does (not only Taige, but also the Three Kingdoms series. . . ), when installing, you will leave relevant information in the registry and my document (that is, the place where KOEI keeps records). You only copied the game file, and he can't read the sound file (there is no information about the relevant path) when running on the new computer.

Just reinstall it.
