RAIDar "update" destroyed my functioning RAIDar installation

WTF???

 

I was happly using the RAIDar app with my ReadyNAS, when I got a message saying an update was available. So I downloaded the installation file (RAIDar.dmg), closed the already opened, older version of the app, and opened the downloaded file.

 

An installation window opened up.The window says "RAIDar_6.4.0, and in it, besides two configuration folders, the only thing resembling an app is a file called RAIDar.app. Since this appears to be an independent, already compiled app, I simply moved it to my Applications folder. Then I remembered that I have a special NETGEAR ReadyNAS folder under Applications, so I moved the file there. Because the NETGEAR folder already had a file with the same name, I chose to replace the old version with the new one. But when I clicked on the new one, a window popped up saying: "Netgear installer is preparing the install4j Wizard which will guide you through the rest of the setup process."

 

So, for the first time in the over 13 years that I've been using Macs, an installation .dmg file contained an .app file that itself is an installation file rather than a stand-alone app! In my experience, most .dmg files do the installation themselves, but when they contain an installation file it's always a .pkg file and not an .app.

 

So I deleted the RAIDar.app file and all associated files, and went back to the .dmg file. When it opened its window, I clicked on the RAIDar.app file, and the installer message reappeared. But this time, after a few seconds a second window popped up. It says:

 

An error occurred:

java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Error log: /private/var/folders/dw/y_ps_c0x401_j98mlsvf0c1m0000gp/T/install4jErrors3001775139611856653.log

 

No problem, I thought. I'll just download a new version of the install file and install from there. So I went to the Netgear site, and downloaded a copy of RAIDar_6.4.0.dmg. It opens a window that's identical to the one before. But unfortunately, it yields the same result as before: the same java.lang error message.

 

Again, I thought, no problem. I'll just download and install an older version and let it give me update messages so I can get up to date. So this time I downloaded RAIDar_macos_4_3_8.dmg. But when I click on it to do the reinstall, I get a window showing a single file: RAIDar Installer.app. At least this time it has "installer" in the name so it's not confused with the RAIDar.app itself. But when I click on it I get the following message:

 

"RAIDar Installer.app is damaged and can't be opened. You should eject the disk image."

 

The message has some more details about the .dmg file, but the above is the important part.

 

So now, thanks to these compounded errors, I've deleted my existing RAIDar installation and don't know how to RAIDar back.

 

PLEASE HELP!!!!
