We have used Microsoft Office Web Components (OWC11.DLL) to put charts onto PI pages - it is great for graphing etc. However, in the last couple of weeks, I think we have had some Microsoft updates rolled-out that have broken things. It is a bit hard to diagnose (so many people with different versions; works OK on some PCs and not others, and various people have different Build numbers for the OWC11.DLL), but essentially: I think it is now broken for people Windows 7.
Quite a bit of googling has shown that Microsoft has officially withdrawn support for OWC, although it can still be downloaded. I have looked at trying to "fix" the existing issues, but I think that ultimately I need a new control for displaying data.
What are other people using for this?
Note: I need a solution that DOES NOT involve third-party controls, unfortunately. I need something that can be rolled-out to users who have locked-down PCs (i.e. don't have administrator rights).
