If you have landed on this page, you are likely experiencing one of two situations. Either you have finished using the Quantv Portable application and want to reclaim disk space, or (more commonly) the software is behaving erratically—failing to launch, throwing error messages, or refusing to update.

Unlike traditional software installed via an .exe or .msi file, "Portable" applications (like Quantv Portable) do not use the standard Windows Registry or add entries to the "Add or Remove Programs" list. While this makes them convenient to run, it makes them confusing to uninstall.

This guide provides a step-by-step breakdown of exactly how to uninstall Quantv Portable manually, how to remove its leftover data, and how to troubleshoot common removal issues.

QuantV replaces or adds custom texture and shader files. Delete or restore these:

Quantv Portable generally does not write to the registry, but if you ever clicked "Register file associations" (e.g., associate .m3u or .mp4 files with Quantv), there will be leftover registry keys.

Warning: Incorrect registry editing can break your Windows installation. Back up your registry first.
