7.0和7.1版本安装后 VISA configure serial port 这个函数不能用，导致串口通信不能实现，请问有人碰到过这种问题吗？怎么解决的呢？谢谢！
错误代码：
Error -1073807202 occurred at Property Node in VISA Configure Serial Port (Instr).vi->Untitled 1
This error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input.
我查了一下 -1073807202 错误代表的是：
A code library required by VISA could not be located or loaded.

Make sure that NI-VISA or the NI-VISA Run-Time Engine is installed on the computer. This error suggests that NI-VISA is not installed, or there is a problem with the installation. To remedy this, uninstall any existing versions of NI-VISA on the machine. Then, either reinstall the same version of NI-VISA, or upgrade to the latest version of NI-VISA (linked below). If problems persist after reinstallation, browse the information included in the VISA Troubleshooting Wizard (linked below) for additional suggestions.
