Problems to make an executable VI from a DLL

Hi people,

I have 2 of the DLL, the first (rfid.dll) is imported into labview and contains some 55 functions. 1 of them has an internal memory management and too complex to work properly. So I have a second (wrapper.dll) dll that contains a simplified access to memory. However, on the second dll import, I get

No executable VI
The VI is not executable for one of the following reasons:
1. the shared or a file-dependent library is not installed. To make the executable VI, you must install the shared library and all files supported on the computer on which you run the VI.
2. a required custom control may be empty or cannot be found. To make the executable VI, manually update the custom control.
3. the VI contains a parameter with an unsupported data type. To make the executable VI, you must replace the cluster indicator or empty the wizard generates a control that uses the data types supported.
Retrieve attached RFID Radio list Wapper.vi
test.VI

Note that test.vi is not either executable, if I test function in the second dll, then test.vi is executable. It would seem that the second dll is unable to locate the rfid.dll.

Any help please.

Robert

It seems that labview can solve the DLL using the DLL using the DLL

My first rfid.dll used 2 other DLL that were in the path given, that has been resolved and I was able to import.

The second wrapper.dll used the rfid.dll and it appears that the produced DLL in the same way, that he was unable to go to the next level.

I fixed it by copying all the DLL in that I needed

C:\Program NIUninstaller Instruments\LabVIEW xxxx
