AppCompat: Applications writing to C drive etc

[NZSchoolTech]

What are the issues with legacy applications which may be writing data into
their install folders, either something like C:\KEYS or C:\Program
Files\Keys?

My understanding is that the application is supposed to write into
Application Data folders either in Local Settings or in the roaming part of
the user's profile.

I am having trouble with an old app that we have been able to get working on
XP by giving the user administrative rights over a machine. In Vista this is
not sufficient any more.

Hi,

The issue is that the program cannot write to the program folder during
normal runtime mode. It can only do so if run elevated (specifically invoked
admin privileges). By the way, C:\Keys would not be a protected system
folder, so the above wouldn't apply. C:\Program Files\Keys would be.

When virtualized, they run from C:\Users\<user>\appdata.
