Hypersnap uses a proprietary installer, ie: no switches will work.
Several things you can do:
-copy the files and export reg entries...
-use a script (like
this one)
-capture install and repackage as .msi file
(...)
As for vueprint pro (never used it), if it works like vuescan, just copy the installed files (the license is a file inside the directory) and the shortcuts. (Althought it seems like it adds a bunch of reg entries/shell integration - that you could easily capture with something like RegSnap - that's if you want to keep it) You could make it into a sfx too (or again capture the install, or autoit, ...)
(asking for them over and over again will not magically make the installers have switches to install them silently... sometimes, there just aren't any)
