Well, when you uninstall a program, sometimes the entries are
still kept in your registry
However just one or 2 strings of binary codes of the registry
are not enough to bring the program back to work
What you can do is to go to
START>RUN>type in "regedit" without the " ",
and
expand(by clicking on the small arrow at the side of the
word)
1. HKEY_LOCAL_MACHINE ,
then expand
2. SOFTWARE
In that section you can see many names of programs which are
installed on your computer, maybe the program you just uninstalled
is still left in the registry, and the name of the program will be
reflected there, thus u can re download the program and unlock your
files
Remember to 'unexpand' after viewing
NOTE: WRONG EDITING OF THE
REGISTRY WIILL CAUSE PROGRAMS TO CRASH
