libgcc_s_sjlj-1.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libgcc_s_sjlj-1.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like dumpcap.exe - to follow. These files were created so that multiple programs (eg. Wireshark) could share the same libgcc_s_sjlj-1.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when libgcc_s_sjlj-1.dll is attempted to be loaded either when Wireshark is starting up, or in some cases already running. Some of the most common libgcc_s_sjlj-1.dll errors include:
- Access Violation at address - libgcc_s_sjlj-1.dll.
- libgcc_s_sjlj-1.dll could not be found.
- Cannot find C:\Program Files (x86)\Wireshark\libgcc_s_sjlj-1.dll.
- Cannot register libgcc_s_sjlj-1.dll.
- Cannot start Wireshark. A required component is missing: libgcc_s_sjlj-1.dll. Please install Wireshark again.
- Failed to load libgcc_s_sjlj-1.dll.
- The application has failed to start because libgcc_s_sjlj-1.dll was not found.
- The file libgcc_s_sjlj-1.dll is missing or corrupt.
- This application failed to start because libgcc_s_sjlj-1.dll was not found. Re-installing the application may fix this problem.
Your libgcc_s_sjlj-1.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wireshark), or deleted by a malware infection. Furthermore, libgcc_s_sjlj-1.dll file corruption could be caused from a power outage when loading Wireshark, system crash while loading libgcc_s_sjlj-1.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
