[wix-users] How to fix old broken installs

[Wheeler, Blaine (DSHS/DCS)]

If it is badly scrambled, I would start over with new GUIDs. If you have many shared controls try to use wixlibs first and then consider fragments as a second choice.

OK, I need some advice

One of the big reasons I'm moving to WiX is we have some broken installs - and in particular, boke DE-installs, all of which were done by my predecessors in Installshield

Well, it turns out, they were installing the same component in multiple installs, but with DIFFERENT GUIDs, so reference counting etc is broken, so if the user de-installs product A that shares a DLL (or registry etc) with product B, we get hosed

So, what is the best way to go forward?  If product A is the main product, and product B required Product A - change the GUIDs in Installer B to match product A (actually, yes, I know fragments etc so they match), or a full set of NEW GUIDs (again with fragments etc) and write off any "old" installs?  Something else?

Charlie
