Since the dawn of Windows programming there has been one major
directive - "Play well with others". *Others* includes the operating
system as well as other applications and services. Rules and Taboos
have annoyingly changed over the years, but nonetheless a Windows
programmer needs to adapt to a current situation.

You are correct - volatile data should not be stored in the "Program
Files" folder/s, Period. Therefore, reengineer your application,
Period. If it takes more than a few minor changes to conform to the
new Taboo, then your application is in serious need of a "cleanup"
anyway, as it is too dependent on physical, and possibly hard-coded,
locations.

Suitable folders for this data can be found by reviewing the 'special
folders' Windows provides for this and other purposes:
CSIDL
http://msdn.microsoft.com/en-us/library/bb762494.aspx
KNOWNFOLDERID 
http://msdn.microsoft.com/en-us/library/dd378457.aspx
[There are other advantages to storing data in known locations as well
- backups become easier, roaming profiles, multiple user or single
user configurations, home or corporate environments, updates,
maintenance, ... all go more smoothly.]

If you need to fiddle with the Application itself - launch an
installer. [Running an installer to update *data* strikes me as a
needless abuse. <g>]
