What is the easiest way to write from a custom action into the Registry table?
I'll try to avoid doing patches because of a few reasons: 1) I will need 4 of them - there are 2 bad versions in the wild, and each has 32 and 64 bit variations 2) I will need to keep the patches around for a long time (basically any new version needs to include them) 3) Installing a patch will require a separate elevation prompt The patches will be my plan B if the registry table trick fails.
