Error while using LabVIEW 8.2.1 Dll from Visual C++ 6.0

[Bhat_Gopal]

I am getting an error while using a LabVIEW 8.2.1 dll from Visual C++ 6.0 application. This is what I am doing:

1) Created a dll using LabVIEW 8.2.1 (I used a tutorial from NI knowledge base: "Creating DLLs from 6.0i". It is a temperature conversion VI; input DegreeF and get DegreeC out). Instead of LabVIEW 6.0i, I used 8.2.1. It created the dll Convert_Temp.dll successfully.

2) Then I created a Visual C++ 6.0 application (used a tutorial from NI knowledge base: "Calling a DLL from Microsoft Visual C++ that was Generated by LabVIEW 6i). I could build the project and create an executable application F_To_C.exe.

3) Then copied the LabVIEW dll Convert_Temp.dll into the folder where F_To_C.exe resides. Using windows explorer, went into that folder, and executed the application.  I got the following error:

System Error 998 while loading the LabVIEW run-time engine (C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\8.2\lvrt.dll).

Convert_Temp requires a version 8.2.1 (or compatible) LabVIEW Run-Time Engine. Please contact the vendor of Convert_Temp to correct this problem.

I checked the folder: C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\8.2\. It has the file lvrt.dll.

So why am I getting this error?

sounds like you need to install the LabVIEW 8.2.1 runtime. Not the 8.2 runtime engine.
