"The feature you are trying to use is on a network resources that is unavailable."
Damn it.
The installer is looking for "silverlight.msi" on:
H:\fe03861a8d7962b335f796f91dcbe7
H:\49d533773b23642bfe19
OR
H:\183b5209132feb5a29
Each and every time I execute the stand-alone installer, it creates a different named folder for the installation files. Then when it abends, guess what happens? That's right - pooof - nada folder no more anywhere.
What kind of F'd up BS is THAT Microsoft? If there's ANY doubt WHY people are trying to F up YOUR GD shit.
FWIW: I've recently noticed that a significant number of MS product upgrades/updates are installed fromn a lot of high lettered partition sources; the thing is that those installation sources don't exist after reboot.
