Sources of ASP Problems

Common Problems Opening ASP Files

Mozilla Firefox Removed

If you attempt to load your ASP file, you experience a message such as "Can't Open ASP Files". If this is the case, it's usually due to the fact that you do not have Mozilla Firefox for %%os%% installed on your computer. This will prevent you from double-clicking to open the ASP file because the OS doesn’t know how to handle it.

Tip: If you know of another program that can open your ASP file, you can try opening it by selecting the application from the programs listed.

Mozilla Firefox is Out-of-Date

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

Tip: Find clues on the correct software version by right-clicking your ASP file and clicking "Properties".

Ultimately, most of the difficulties opening ASP files are due to having the wrong version of Mozilla Firefox installed.

Additional ASP Opening Issues

Errors opening Active Server Page files can still occur even with the latest Mozilla Firefox software installed on your computer. Other ASP opening errors can be created by other system problems inside of %%os%%. Other contributing causes:

• ASP file references in the Windows Registry are broken
• Mistaken removal of the Windows registry ASP description
• Incomplete or bad installation of a software application associated with the ASP format
• Your ASP can't be loaded properly (file corruption)
• Your ASP is infected with malware
• Drivers associated with ASP software need to be updated
• Windows has inadequate resources to open your Active Server Page file
