Understanding SED Issues

Troubles Opening SED Files

Microsoft IExpress Wizard Not Present

If you attempt to load your SED file, you experience a message such as "Can't Open SED Files". If so, it typically means that you don't have Microsoft IExpress Wizard installed for %%os%%. Your operating system cannot associate your SED with Microsoft IExpress Wizard, so double-clicking the file won't work.

Tip: When another SED application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Microsoft IExpress Wizard is Out-of-Date

In some cases, you might have a newer (or older) version of a IExpress Self Extraction Directive File file that is unsupported by your installed application version. If you've got the wrong version of Microsoft IExpress Wizard installed, you'll need to install the correct version. This problem is predominately due to having a IExpress Self Extraction Directive File file version that was created by a newer version of Microsoft IExpress Wizard than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of SED file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Regardless, most of the SED file opening problems relate to not having the right version of Microsoft IExpress Wizard installed.

Additional SED Opening Issues

Although you might already have Microsoft IExpress Wizard or another SED-associated software installed on your computer, you can still encounter problems opening IExpress Self Extraction Directive File files. If you are continuing to have errors with loading SED files, other external issues might be to blame. Problems unrelated to software:

• Corrupt Windows Registry file path references for SED
• Corruption of the SED file description inside the Registry
• Invalid installation of a SED-associated program (eg. Microsoft IExpress Wizard)
• Your SED file is corrupted (issues with your IExpress Self Extraction Directive File file itself)
• Past or present virus infection has affected your SED
• Device drivers for SED-related hardware are out-of-date
• Windows cannot load your IExpress Self Extraction Directive File file due to insufficient resources (eg. RAM)
