MP3Rocket: "Unable to access jarfile lib\MP3Rocket.jar"

by jwolfeld / April 28, 2013 7:56 AM PDT

MP3Rocket, both upgrade and fresh install, getting error message "Unable to access jarfile lib\MP3Rocket.jar" on startup.

This worked as recently as yesterday, before I accepted the upgrade. Now even when I uninstall and reinstall the old version (which I happened to have kept), I still have this problem. This isn't a problem with Windows Java settings. The jar file itself is simply not there where it's supposed to be.

Have tried turning off all virus scanners and intrusion detectors, as well as starting the installer As Administrator, no change. Anybody have any ideas?

In reply to: Did you see this

Thanks. Tried it, but it didn't work for me. I also found that MP3Rocket leaves a large number of files under C:\Users\(my-user-name)\AppData\Roaming\MP3Rocket, even after uninstall (I'm on a Windows 7 system). I tried deleting them as well before reinstalling to a new directory, but no success.

I noticed that not only is the MP3Rocket.jar file itself missing, but in that lib directory there are a lot of xxx.pack.gz files, and no jar files at all. I'm thinking that MP3Rocket is just one of many files that should be there which aren't, because the installer was somehow unable to unzip and unpack all of these files.

Does that ring any bells with anybody?

I recall that I installed 7zip on my computer not too long ago. I uninstalled it and tried MP3Rocket again, but there was again no success.
