It is prefered that you do a fresh install, as some of the newer features depend on those features being represented in the configuration files. However, if you are determined to do an upgrade, the instructions follow.

Upgrading Guiprep involves installing the new version in a directory and copying a few files over from the prior install. This document walks you through all the steps.

This document assumes you have Guiprep installed in c:\guiprep. If you have this installed in a different location, you will need to adjust the paths below accordingly. Despite the instructions using Windows paths, the overall steps below work for all operating systems.

1. Backup your old installation. It is highly recommended that you backup your prior Guiprep installation before continuing.
2. Rename your old Guiprep directory (eg: c:\guiprep) to a new one (eg: c:\guiprep-old).
3. Follow the instructions in INSTALL.md to install Guiprep for your operating system, including any helper applications, noting that on Windows, if you have not already done so, you must install Strawberry Perl before trying to install and run Guiprep. Note the requirement to run install_cpan_modules.pl to ensure all necessary Perl modules are installed.
4. Review and possibly copy over changes made to Guiprep files.
   • The setting.rc file stores Guiprep configurations. This file is automatically generated by Guiprep if it doesn't exist. Newer versions of Guiprep will include updated defaults. It is recommended that you do not copy this file from your old version but let the new Guiprep create the file afresh. You may then have some preferences you want to change within Guiprep which will be saved in this file.

You can now run Guiprep from the new installation directory.
