Troubleshooting Problems Opening ASPX Files

Common ASPX Opening Problems

Safari Isn't There

Double-clicking your ASPX file prompts the message "%%os%% Can't Open ASPX File". Customarily, this means that Safari is not installed on %%os%%. This will prevent you from double-clicking to open the ASPX file because the OS doesn’t know how to handle it.

Tip: If you have another software that you know opens ASPX files, you can select it by hitting the "Show Apps" button.

Wrong Version of Safari is Installed

Sometimes your installed version of Safari won't support your Active Server Page Extended ASP.NET Script file. If you've got the wrong version of Safari installed, you'll need to install the correct version. Your Active Server Page Extended ASP.NET Script file was probably created by a newer release of Safari than what's currently installed your computer.

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

Summary: In either case, the majority of problems opening ASPX files are related to not having the correct software application installed on your computer.

Other ASPX File Opening Causes

In the majority of cases, installing the right version of Safari will resolve your issue. If you're still experiencing problems opening ASPX files, there could be other computer problems. These other problems include (listed in order from most to least common):

• Invalid ASPX file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Corruption of the ASPX file description inside the Registry
• Invalid installation of a ASPX-associated program (eg. Safari)
• File corruption affecting your ASPX file
• Your ASPX has adversely impacted by malware
• Device drivers of the hardware associated with your ASPX file are corrupt or out-of-date
• Insufficient system resources to successfully open Active Server Page Extended ASP.NET Script files
