| 8 | == Installing ECW SDK == |
| 9 | |
| 10 | The GDAL ECW Plugin requires the ECW 3.3 Runtime libraries which the end user is required to download and install directly from the Erdas Web Site directly. |

| 14 | After installation, please copy the .dll files in the redistributable\vc71 directory somewhere appropriate, like C:\windows\system32. |
| 15 | |
| 16 | eg. |
| 17 | {{{ |
| 18 | copy C:\"Program Files\Earth Resource Mapping\ECW SDK\redistributable\vc71\*.dll" C:\windows\system32 |
| 19 | }}} |
| 20 | |
| 21 | Note that downloading and installing these DLLs requires agreeing to a license. Please review the license terms carefully. |
| 22 | |
| 23 | It is imperative that the VC7.1 ECW 3.3 SDK binaries be used. Any other ECW (NCS*) DLLs are unlikely to work properly. Failure to install the correct ECW libraries will normally result in a popup message reading "This application has failed to start because NCSEcw.dll was not found." or a console error report like: |
