When installing new RTI packages that may overwrite the contents of previous packages—for example, when installing a patch—the RTI Package Installer will create a zip file that contains a backup of all the files that are overwritten.
To avoid using unnecessary disk space, the installer will delete the previous backup file after the latest backup zip file is created. This means that there will only be one backup at a time.
To revert changes made by patching, you can unzip this file and copy files back to their original location. Note that this manual step will not be reflected in RTI Launcher, which will still show the last installation version.
When installing a new RTI package that overwrites the libraries in the <NDDSHOME>/lib/<architecture> directory, a backup will be created of all the previous libraries in the <NDDSHOME>/lib/<architecture> directory. That backup will be created in <NDDSHOME>/lib/<architecture>/<current_installed_version>.
For example, if you install a patch version 5.2.0.1 to the RTI core libraries for i86Win32VS2010, your 5.2.0 libraries will be copied into the following directory before the 5.2.0.1 libraries are installed: <NDDSHOME>/lib/i86Win32VS2010/5.2.0.
If you install another patch later, before overwriting the 5.2.0.1 libraries, they will be copied into <NDDSHOME>/lib/i86Win32VS2010/5.2.0.1.
