Uninstalled Labview 8, but ActiveX control for 3D charts still installed.

[pughjl]

I'm using Labview 7.1.1. I installed a trial version of 8 and later uninstalled it however the CWGraph3D control is still the one distributed with Labview 8.

The code works on my machine still using 7.1.1, but when I build a distribution package, the user gets an error stating the control is unlicensed. OK, how do I roll back the control to what should work with Labview 7?

Hi pughjl,

Since the CWGraph3D control is an ActiveX object, you should be able to use it no matter what as long as it is properly registered and such.  Were you able to successfully build your application in 7.1.1 before you installed LabVIEW 8 for evaluation?  Also, does the error appear on your development machine or only on other machines?  The problem could be that the ActiveX object isn't registered on your target machines.  Please check out this discussion forum post which has some helpful links and information for building applications with the CWGraph3D.

The activeX control gets installed on the users system, but the version doesn't match his run time.

He gets an error: Error loading control. A newer version is needed. Default settings for the control will be used.

The 3D chart controls displays, but in black and white with the words "Evaluation Copy" in red across the top.

I tried uninstalling the remaining version of Labview and reinstalling. The ActiveX control is still at version 1.6.

I think I'll remove the .ocx file and remove references from the registry and try reinstalling.

It turned out I had saved a vi with the newer ActiveX control loaded. I needed to remove the ActiveX control and put it back with Labview 8 uninstalled.
