This error indicates that the dynamic link library file responsible for compression and decompression processes is either not found or has been compromised. The most common cause of this issue is file corruption due to malware or accidental deletion, though hardware issues like bad sectors on a hard drive can also be culprits. Before trying the methods below, it is recommended to reinstall the affected application first, as this can sometimes resolve the issue without additional steps.
1. Download the DLL File
Downloading the zlib.dll from a reliable source can resolve the missing file issue. Once downloaded, go to your PC’s Downloads folder and extract the DLL’s setup file. Move the extracted file to the application’s base folder that had the missing zlib.dll error. This step ensures the application has the necessary file to operate properly. Note: Ensure you download DLL files only from a trusted and reliable source to avoid potential malware.
2. Update Windows
Windows updates bring new features and fix known bugs and compatibility issues. Keeping your system updated improves its overall performance and stability.
3. Scan for Viruses
Malware can disrupt applications and disguise itself as a DLL file, preventing your software from operating. Running a virus scan can help identify and remove these threats.
4. Use System Restore
System Restore saves your system settings before software installations or Windows updates, allowing you to revert to previous settings if issues arise. If this error appeared recently, you could use System Restore to revert Windows settings to a working state. Note: Restoring will delete any programs or updates installed after the restore point. Your passwords will also revert, so it’s recommended to create a password reset disk for Windows passwords.
