Installing classic sports titles like on modern Windows operating systems can sometimes run into abrupt technical roadblocks. One of the most frustrating obstacles gamers face is the archive extraction failure, typically accompanied by the message: "An error occurred when unpacking: Unarc.dll returned an error code: -6" (or error code 6). search results show several general guides for fixing unarc
Finally, meticulous attention must be paid to the extraction process itself. A common mistake is attempting to run the installer directly from within a compressed archive (e.g., double-clicking setup.exe inside WinRAR). This leads to fragmented or incomplete file access. Always extract the entire contents of the archive to a simple, short path on your local drive, such as C:\FIFA13_Setup . Avoid using nested folders, desktop locations, or paths containing special characters or spaces. For ISO files, either extract all contents using 7-Zip or mount the ISO as a virtual drive (in Windows 8/10/11, double-click the ISO file), then copy the setup files to a local folder before running. Running the installer from a virtual drive or within an archive is a proven trigger for error -6, as the decompression engine struggles to maintain consistent read/write operations across virtual layers.
