We upgraded to ArcGIS 10 yesterday.

Tried to add our ECW aerial imagery and got an error message:

"Invalid rater dataset. Failed to create raster layer."

These ECW files were opening just fine in Arc 9.3.1 two days ago.

What's the problem?

(ArcInfo license, btw...)

You should be able to view ECW files in ArcGIS Desktop. Please contact Support.

Attempted to load ECW files that work in ArcView 9.2 into ArcView 10, the images load but appear inverted.

Files projected as GCS_GDA and ECW header is okay.

Any ideas?

Also having this issue intermittently since upgrading to ArcGIS 10.0. Usually fixed with a restart of the PC~

Unaware of the cause?

I'm having the same problem.  Has anyone found the fix?

Resolved the problem re inverted ECW images.  Had to use ECW Header Editor and change the setting regarding direction of Y coordinates.  In the southern hemisphere the latitude coordinates increase downward, 0 to 90. But realising that southern hemisphere latitude numbers are defined as a negative number then the Y coordinate would in fact increase upwards, -90 to 0.

I had the same issue.  When I contacted ESRI Support, they told me how to fix it:
Start button > Run > regedit
Drill down to HKEY_CURRENT_USER > Software > ESRI > Desktop10.0 > Raster
Rename the folder from Raster to OldRaster

It worked for me.  Good luck!

This provides a temporary fix for me, but the error has recurred a number of times and I have to repeat it again...

Can we have a fix that lasts, please?

I'm affected by the "Invalid raster dataset. Failed to create raster layer." error on an ECW image at ArcGIS 10 too. 

Editing the registry as suggested above worked so hopefully fix will survive next reboot. 

Does anyone have a bug number (NIM...) for this?

As expected this issue returned after I installed the Desktop part of the ArcGIS 10 (Desktop, Engine, Server) Raster Format patch from http://resources.arcgis.com/content/patches-and-service-packs?fa=viewPatch&PID=17&MetaID=1648

I left ArcMap 10 open while editing the registry but had to then close and re-open ArcMap before seeing the workaround take effect.

Anyone know an NIM bug number for this that we can use to track when it is fixed?
