Did you downloaded the full zip file and unzip it into an empty folder? In a previous message you mentioned you tried to update a previous version. Before you unzip and start the new install, you should ensure you do not have an existing :\Documents and Settings\<user>Application Data\SQL Developer\system1.5.1.54.40 folder.

What platform are you on?

Sue

This is happening on multiple machines?

From what I can tell, this error is generally an issue with Windows when there have been changes to the drives that are visible and something is expecting to find a drive or directory somewhere and that doesn't exist. For example, card readers or iPods mounted as disks might be associated with something.

SQL Dev is probably hitting it because the calls we make to get the list of directories, etc. is causing Windows to scan for this missing mounts.

I'm sorry I can't be more specific, but from what I can tell, it's a problem with the machine configuration

John,

I am seeing this same issue here on multiple (older) Windows 2000 machines.
The one thing they have in common is a floppy disk drive.

Once I insert a floppy disk into the drive, the error goes away and
SQL Developer starts up. This behaviour has begun with the version 1.5
of SQL Developer. Earlier versions are unaffected.

Hope this helps.

Armin

Addendum: PCs with Windows XP and a floppy drive seem to be unaffected as well.

Hi I have the same error on my windows 2000 VM ware: As you see below I use the E drive and C drive for the software. I checked all paths and it looks fine. The error is not so critical but annoying.

Has anyone worked out an answer/workaround to this one? I see it's quite an old post but there don't seem to be any others on the subject. I'm having the same problem with the latest sql developer. I've tried three different computers (all on win2kpro though!) with and without importing old settings, with and without deleting previous settings folders! I've tried it from a local drive as well as a key, but no joy. The other thing I've noticed is that if I import old connections and then close sql developer they disappear again next time I open it. I'd be very glad if someone could help me figure out what's going on!

Thanks!
