Recive error code 0x8482 with FP_Open in LabWindows

[j_chandler]

PC Configuration:
Windows 2000
LAbWindows/CVI 5.5
FieldPoint driver 4.0
FP1600 used for communications with the following modules:
FP-DO-403
FP-RLY-420
FP-AI-100

When I use the measurement studio to operate the modules like the FP-DO-403, I have no issues properly operating the system. However, when I make the FP_Open function call in LabWindows/CVI, it returns the error 0x8482 IA_MGR_DLL_Load_Failed. I did some searching here and found that I did not have the FPCVIMgr.dll on my system. I downloaded it and installed it in my WINNT\system32 directory and rebooted the system. This accomplished nothing. What do I need to do to make this error go away and be able to command my FieldPoint modules properly in
my software?

j,

The following Knowledge Base discusses one solution for error 33922 (0x8482).

From your description it sounds like you don't have support for CVI installed on your computer. Try running the FieldPoint installer again and ensure that you have support for LabWindows/CVI selected.

I saw that and tried it before I posted the message. I installed 4.0 and installed support for CVI as well as all other compliers and LabView. It made no difference other than changing a FieldPoint object file making my code not compile. I will retry this today maybe with an older version of the software (Ver 3.0, the original software was 2.0) and post if it works.

The error I received when using the new object file was:

Aborted load of object module
"c:\MeasurementStudio\cvi\FieldPoint\FieldPoint.obj". The file
"c:\MeasurementStudio\cvi\FieldPoint\FieldPoint.obj" does not match that used by the current compatibility mode.
A little history on this system, it was almost finished in December 2001 and was that put into storage. The system had Windows NT and FieldPoint Ver 2.0 and the FieldPoint calls worked then. It was pulled out of storage in May 2004 and I was assigned to finish the task (I was not involved in the original development). In trying to get this system to work due to conditions caused by 2.5 years in storage, I have had to upgrade the OS to Win2000 and I upgraded the FieldPoint
Driver software to Ver 4.0.1 and now no CVI calls work for the FP.
Also since I have reinstalled the FieldPoint Ver 4.0.1, the Project file is now looking in the
C:\MeasurementStudio\cvi\bin folder for an obj and fp file. If I put the new obj file there I get the aforementioned error message, however if I put the old obj file in there, I get a new error on my FP_Open error code 0x8481 IA_MGR_SERVER_DLL_NOT_FND.

Problem solved

I found an old copy of the FieldPoint Driver Ver 2.0 and installed it back on the PC. Errors went away and the code executes as expected. Thanks.
