"an error occurred saving the activex control"

Question

I'm trying to compile an executable in Labview 5.1. When I run the build app, it gets about half way done then pops up the error:
"an error occurred saving the activex control"
After clearing the error message, it proceeds to go through the motions of compling the app, but no exe is generated.
The design mode progam run operates fine, and it saves fine as well in design mode.
Thanks!

wawatts,
Though Brian and I got a broken arrow because we didn't have the necessary ActiveX component installed, I imagine you get no errors on the development system because you do have the component.
This problem would be much harder to pin down on your side given the lack of development-environment errors and the sprawling design of the main VI. One possible troubleshooting approach would be the LabVIEW Find functionality (Edit >> Find). ActiveX functionality typically involves the use of Property Nodes and Invoke Nodes, so if you search for any Invoke Nodes (Select Object, then Functions >> Communication >> ActiveX >> Invoke Node) in the scope of your main VI and its subVIs, you could perhaps have turned up some hits that take you to the subVI that has the control that is presumably causing the problem.
Unfortunately, I fear that finding the problem area doesn't solve the problem. It seems to me that either the LabVIEW app builder or the ActiveX component is doing something unexpected or nonstandard that is leading to the error message.
I'm going to stick to my "upgrade the software as much as possible" guns:
1. Install the LabVIEW 5.1.1 patch I linked to above, if it isn't already installed. There were fixes to the development environment and changes to the app builder that might resolve your problem. This is a free patch.
2. Consider upgrading the ActiveX control. I think that the latest version is called IntuiLink for 54600-series Oscilloscopes, Version 3.1, and it's available here on the Agilent site.
It was easy to do a simple test using your Xezgetsetup.vi on my system (LabVIEW 7.1.1, XP) with the updated ActiveX control. First, I installed the Agilent software. Then, I right-clicked inside the ActiveX control on the front panel of Xezgetsetup.vi, chose Insert ActiveX Object, and selected Agilent 54600 Scope Control from the list. Then I had to go to the block diagram and relink a few of the property and invoke nodes by just left-clicking on broken nodes and re-selecting the items that your code was already displaying. That fixed the VI so that it would run again.
Then I built that VI into an EXE and got no errors.
Perhaps all this proves is that you would have clear sailing if you upgraded to LabVIEW 7.1 and got the most recent Agilent ActiveX control--and maybe this is a good reason to bite the bullet and do that upgrade now--but it's certainly possible that you can do the same thing in 5.1 and solve your problem. Worth a shot.
Hope that helps,
John
