When you clicked the Download button in the Account Manager, you were prompted to open or save the file. If you saved the file, after the download completes, you need to locate the file lne20_setup.exe and open it to begin the installation. If you cannot locate the file, download it again. Log into your account and select the link to download Express 3.0.
If you get an Invalid win32 application error when you try to open the file, you need to delete the file and download it again. The file was not completely downloaded, which caused the file size to be smaller than the original source file.
If you see a box with a list of applications to open the file, it's possible that the file extension .exe was somehow lost from the Express 3.0 installation file. You can easily check and add the .exe if needed. Right-click on the file and select rename to add the .exe file extension.

Express 3.0 accelerates the downloading of Web page images by first pre-compressing the graphics they contain. This is just one of many techniques that Express 3.0 uses to improve Web page load time. By default graphic images are delivered to your Web page in slightly compressed form that balances speed of delivery with graphics quality. In some cases you may notice a degraded graphic and want to see the original quality. Click here if you would like to view an image or Web page with original quality. If you uninstalled Express 3.0 and you need to remove degraded images from your browser cache, click here.
