Usually, but you never know. If it fails, how easy is it to
get back to the previous version? What else might accidentally
break? (Replacing DLLs that might be used by others?)
Then there are the funny ones. I have seen installers, even fairly
new ones, fail after improperly determining available disk space
or virtual memory. A system with over 2GB virtual memory available,
computed in signed integers, comes out negative. There is a
similar failure in the disk space calculation.
Many installers want you to stop all other programs before
they run. Sometimes that is necessary, but more often it
isn't, and negates the whole idea of running multiple
programs at the same time. Similar for ones that require
a reboot, though many don't even though they say that they do.
Most ask first, but not all.
