You may install PNotes by two different ways: either by downloading and extracting
ZIP archive, or by downloading and executing standard setup program. Deinstallation
could be done accordingly: in case of ZIP archive just delete the PNotes folder,
in case of standard setup - use uninstaller which ships with installation.
Which way is better - depends only on your preferences.
Users installed the program with standard installer (NOT ZIP archive) of version 8.0, have
to backup "data" folder and "notes.ini" file before installing new version (because
of bug in setup script, these folder and file are deleted during uninstallation,
regardless of user's inhibition).
Tip: if you are on Windows Vista or Windows 7 under restricted account - install
it into root folder ("C:\"), instead of "C:\Program Files" (x32 system) or "C:\Program
Files (x86)" (x64 system) in order to avoid UAC conflicts.
Also at this page you can download help files, source code of program and various
files from previous version.
