There are several times when your trial software has expired and you may not be able to reinstall it over again. However there are several ways in which you can reinstall trial software after the trial period has completed.
The Addictive Tips blog, lists out couple of hacks that will allow you to reinstall trial software after the trial period has completed.
Backing Up Registry
The best way is to make a backup of the registry before installing any trial software. And when finally your trial has expired, you can uninstall the software, restore backup and try installing the software again.
This may indeed be one of the ways to hack trial softwares, however we would not be pretty comfortable with doing this, since registry changing every time you use the computer and restoring your registry to a backup, after having used a trial software for 30 days is pretty risky.
Using Process Monitor
Run Process Monitor and install the trial software. Now find which key the software has added or modified, and note down the name and path of the key. Once your software trial period has expired, you can revert back the changes and uninstall the software.
This method seems to be a safer approach and can be easily accomplished. Hack and Mod Tips via Addictive Tips.
