What are Default.browser Error Messages?

General Default.browser Runtime Errors

Default.browser file errors often occur during the startup phase of PrimoPDF, but can also occur while the program is running. These types BROWSER errors are also known as “runtime errors” because they occur while PrimoPDF is running. Here are some of the most common Default.browser runtime errors:

• Default.browser could not be found.
• Default.browser error.
• Default.browser failed to load.
• Error loading Default.browser.
• Failed to register Default.browser / Cannot register Default.browser.
• Runtime Error - Default.browser.
• The file Default.browser is missing or corrupt.

Most BROWSER errors are due to missing or corrupt files. Your Default.browser file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with PrimoPDF), or deleted by a malware infection. Furthermore, Default.browser file corruption could be caused from a power outage when loading PrimoPDF, system crash while loading or saving Default.browser, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.
