The PATH issue has nothing to do with your error messages.
Python25.dll is normally installed in the C:\Windows\System32 folder,
not C:\Python25, so whether or not c:\Python25 is in your PATH is
irrelevant to whether it will be found (in C:\Windows\System32).

The facts as far as I can tell are:
a) Some application in your startup is trying to link to/load
Python25.dll but failing as per the message you posted.
b) You've uninstalled Python 2.5, so a) is not really surprising.
c) The application (whatever it is) will *NOT* automatically start
using the newer Python27.dll because you've installed Python 2.7.
These are considered seperate/distinct versions of Python.

Your options to get rid of the message is:
a) Reinstall Python 2.5
b) Remove the application that depends on Python 2.5 (that is
expecting it to be present.)

To add: I'd be careful of 32 bit/64 bit issues -- If the application
trying to run is in fact 32 bit then you should probably be installing
the 32-bit version of Python, otherwise it probably still won't find
Python25.dll.  (32-bit applications won't be able to link to 64-bit
dll's, and in any case on 64-bit versions of Windows things get a bit
obscure -- C:\Windows\System32 actually contain 64-bit native dll's
while 32-bit compatility dll's reside in c:\Windows\SysWOW64 but is
presented as c:\Windows\System32 to 32-bit processes by the OS... )
If you don't know whether the application is 32-bit or 64-bit you'll
just have to find out by trial and error.  Install the one and if this
doesn't resolve the problem then remove it again and install the
other.
