Hello Triple_H,
LabVIEW 8.6 was released prior to Windows 7, and as such this isn't a supported configuration- refer to this knowledgebase:
Windows Version Compatibility with LabVIEW
https://www.ni.com/en/support/documentation/compatibility/17/labview-and-microsoft-windows-compatibi...
You'll need to move to a newer version of LabVIEW or an older operating system. All versions of the RIO drivers are available here, with the supported operating systems listed:
