Getting Areca Backup to Work on Modern Systems

Unfortunately, Areca Backup hasn't been updated since 2015.  But, it still works great, and it's an awesome program that can compress and encrypt files into a backup archive that can be transferred to a NAS drive or uploaded to the cloud.  However, getting it to work on a modern system can be a chore.  After installing Areca Backup, when you try to launch the application, if nothing happens, you will need to perform both of the following fixes:

Install 32-bit Java first [Windows Offline], and then install 64-bit Java second [Windows Offline (64-bit)] if you have a 64-bit operating system.  Without the 64-bit version of Java, Areca will not launch on a 64-bit system.

The next step to getting Areca to run is to replace the "swt.jar" file in the lib folder found in the installation directory (default is C:\Program Files (x86)\Areca\) with this one:  http://dinofly.com/files/swt.zip

Once the original swt.jar file has been replaced in C:\Program Files (x86)\Areca\lib with the one linked above, Areca will now open and run properly.

Tested on Windows 7 x64, Windows 10 x64, and Windows 11 x64.
