error loading control. a newer version needed. the default settings will be used

[A.V]

Hi I am using LabVIEW DSC 7.1 for programming my application. My VI contains NI hypertrend which I am publishing on a browser using the web publishing tool. When I open the web browser on a different computer I get this error- Component works  Error loading Control. A newer version needed. The default settings for the control will be used. I have disabled firewall, pop up blocker etc...but for some reason it keeps giving me the same error. I read the knowledge base and it talks something about the .OCX file. I am not sure what I am supposed to do..I also have the DSC runtime installed in my machine. I'd appreciate it if someone could help me with this.

Is the DSC runtime system installed on the client machine?

[A.V]

Yes the DSC7.1 run-time is installed in the client.

Did any other NI software get installed? There's a chance the OCX file got updated to a newer version which could cause these types of issues. You may want to try copying the cwui.ocx (located in c:\windows\system32) from the working machine to the client.

Hi Paul

I tried copying the ocx file frm my working machine to the client..still its giving me the same error. I tried opening the broswer on another machine and it works fine. I even checked the internet options on both the machines and it looks the same.

Hi Paul like you said I uninstalled the IA OPC servers and I am getting the same old error....

Sala,

I did some investigation, another thing we can check on is the hypertrend.dll which is located in the system32 folder as well. Check the versions on this versus your development machine, and if it's not the same, back it up on the client and copy from development.

If you're on a 64-bit OS, OCX files  must be in the folder: %windir% \ SysWOW64 
and not in %windir% \ System32 (only for 32 bits OS)
>> %windir% is  the environment variable that defines the Windows folder! (eg: C:\Windows)

French version:

Si tu es sur un OS en 64 bits, les fichiers .ocx doivent se trouver dans le dossier : %windir%\SysWOW64\

et non pas dans %windir%\System32

>> %windir% étant bien sur la variable d'environnement qui défini le dossier de Windows ! (par ex: C:\Windows)
