datasocket failure with error 1184

[don_h]

I used to have 3 pcs making up a network. They were all running Windows 2000  and Labview 8.5.1 and I was able to use one machine to host a shared variable engine and have the others read and write shared variables to and from it. Now I have upgraded the pcs to Windows 7 and my old VIs no longer work. Even though the shared variable library appears to have deployed successfully I get Error 1184 ( Path not found, FTP login incorrect or no FTP write permission). Is this because of an incompatability between Labview 8.5.1 and Windows 7 or is it a problem with setting permissions in Windows 7. If the latter what do I need to set?

Thanks

Technically, LabVIEW 8.5.1 isn't supported on Windows 7, which means that I can't guarantee that this will work at all (since there hasn't been any testing of 8.5.1 on that OS).

Since you seem to have the program itself running, we'll set that aside (I just want to be upfront about it).

The error itself sounds like it's either a network security issue with Windows 7, or some DataSocket configuration that isn't set up yet.

My guess is the latter. If you freshly reinstalled LabVIEW, then the DataSocket server may not be set up for multiple subscribers.

If that doesn't work, then you may need to check your firewall settings in Windows 7. I believe you can find the port numbers and further info in this KB.

Hope that helps!
