Download the official Inno Setup package (from jrsoftware.org), install it, and find the DLL in its directory. Or use innounp , a trusted open-source extractor that directly integrates the necessary logic. No random DLL files required.

If you see this error while installing a game (common with "repacks"), try these targeted fixes:

Set a (e.g., Initial: 4096 MB, Maximum: 8192 MB) on the drive where you are installing the game. 4. Adjust Antivirus and Permissions
