If installing the latest version does not help, check for OS updates. Support for SHA1 (file signature format, including drivers) has been discontinued and certificates are no longer issued.  
FxSound uses the current SHA-256 format, so Windows 7 requires updates to SHA-2 (sha-256).

Here is some supporting information:

> **Information from another major developer**
