307703_Why can't my VeriStand2017 load two models at the same time

[NaGeiue]

I tried to do an example of CarSim help (the document is attached) and add a CarSim in veristand 2017_ LVRT.dll from CarSim2018 and a dll made from simulink2016b
The following error is reported in deploy, but two separate DLL files can be deployed normally (their log files are in the attachment)

Supplementary note:

1.the compiling environment of MATLAB 2016b is Microsoft Windows SDK 7.1 (c) (the process file of build is also attached)

2.The two DLL files from Simulink build can be deployed.
3.When I deploy, I try the next order. The second DLL file always fails to load

4.I don't know what more information you need. Please leave a message for me to add

I would appreciate it if you could help me solve this problem

The VeriStand Gateway encountered an error while deploying the System Definition file.

Details:
Error -307703 occurred at Project Window.lvlib:Project Window.vi >> Project Window.lvlib:Command Loop.vi >> Project Window.lvlib:Connect to System.vi

Possible reason(s):

NI VeriStand: The specified model is incompatible with NI VeriStand. If you are trying to deploy the model to an RT target, launch the Console Viewer tool to display the console output of the target, which includes information about the source of the error.

Hi, have you solved this problem now?

No.

I find your ID is Chinese pinyin, So I replied in Chinese 

没有

我看你ID是拼音就用中文回复了奥

我放弃了这个路线，改用了Labview和Simulink的联合仿真。一方面，Labview同样可以控制硬件，接收Simulink的数据，起到中转作用。另一方面，Simulink文件在编译Build的时候对文件有要求，很多东西没法用（也可能我没调好），Labview可以直接和Simulink链接，不通过DLL文件调用。

缺点是上下位机通讯延迟会高很多
