There can be many reasons... short term reasons is mosty that time  
doesn't permit and other projects are more important.
Long terms reasons are mostly because other software that is running  
on the same machine has different requirements.

Agreed, often the risk needs to get evaluated and for an internal  
system the risks are usually very low.

Yup

Well, that depends. upgrading does cost, staying at some lower version  
might also cost.
Some companies buy hardware before the end of the year to close there  
bookings,
other companies spend to much year and postpone the project to next  
year.

There is also a risk that new software does work, but doesn't perform  
as well as expected,
or just bails out once a while. Some people say 'Don't fix what is not  
broken' :)

But not upgrading and staying at some version of software XYZ (while  
for us there is no good reason)
is a fact of life.
