╔═══════════════════════════╗
Features:
╚═══════════════════════════╝

· Fixes the "received an unexpected EOF or 0 bytes from the transport stream" error (caused by lack of TLS 1.2 support)
· Fixes the "object reference not set to an instance of an object" error (caused by response compression)
· Fixes the "a call to SSPI failed" error (exact cause unknown)
· Fixes the "input string was not in a correct format" and "bencode data is incorrect" errors (caused by chunked responses)
· Can run interactively or as a service
· Includes mRatio multiple instance unlocker and patcher

╔═══════════════════════════╗
How to use:
╚═══════════════════════════╝

1. Download the attachment and extract it somewhere
2. Run start.bat as administrator; wait until it's fully initialized and leave it open
3. Run install_cert.bat as administrator
4. Open mRatio and configure this proxy in the preferences: type SOCKS5, host 127.0.0.1, port 8080
5. Use mRatio normally

Note that the "mRatio Fixer" terminal window must remain open at all times. You can use install_service.bat to install it as a system service instead. This will make it run invisibly and automatically on Windows startup.

Changelog:
╚═══════════════════════════╝

mRatio Fixer v7
· The correct destination port is now autodetected for all trackers
· Switched from mitmweb to mitmdump to greatly reduce memory usage
· Fixed the "input string was not in a correct format" and "bencode data is incorrect" errors
· Tracker responses are now always fully decoded and normalized before they are passed to mRatio. This slightly increases CPU usage but should future-proof against other errors (e.g. "unknown HTTP response")
· Upgraded TLS cipher list to Windows 10 emulation mode
· Added administrator privilege check to all scripts
· The uninstaller now deletes leftover files from old versions, all the way back to TLS Fix v1 [BETA]
· Left beta stage as development has been active for over a year now

Spoiler Previous versions:

mRatio Fixer v6 [BETA]
· Downgraded mitmproxy and its configuration file to version 4.0.4 (should fix the memory leaks and "specified module could not be found"/"failed to execute script mitmweb" errors)
· Renamed redirect.py to fixer.py
· Added mRatio multiple instance unlocker and patcher
· Several code fixes; notably, yes/no prompts can no longer be bypassed by pressing Ctrl+C
· Reviewed Schannel registry entries

mRatio Fixer v5 [BETA]
· Renamed project from "mRatio TLS Fix" to "mRatio Fixer"
· Updated mitmproxy to version 5.1.1
· Renamed scripts (runme is now start, install is now install_cert, service is now install_service)
· Fixed the "object reference not set to an instance of an object" error
· Fixed the "a call to SSPI failed" error
· Added uninstall.bat script to do a complete uninstall and remove all traces
· Added stop.bat script for those who can't press Ctrl+Break

mRatio TLS Fix v4 [BETA]
· Updated mitmproxy to v5.0.1
· Added the ability to run as a Windows service

mRatio TLS Fix v3 [BETA]
· Preliminary fix for the "specified module could not be found"/"failed to execute script mitmweb" error

mRatio TLS Fix v2 [BETA]
· Updated mitmproxy and its configuration file to v5.0.0
· Added a repair function to runme.bat: you can now delete the file "firstrun" to uninstall and delete the root certificate, then generate and install a new one

mRatio TLS Fix v1 [BETA]
· Initial release

╔═══════════════════════════╗
Known issues:
╚═══════════════════════════╝

· Changes to mRatio's proxy settings do not apply retroactively, so existing torrents will not be affected.
Workaround: remove and readd torrents, or use the procedure detailed at https://www.sb-innovation.de/showthread.php?p=359303.

· If installed as a service, startup may fail with error code 1053. The cause of this is unknown.
Workaround: extract to a different path outside your profile directory and without spaces, e.g. "C:\mRatioFixer".

· stop.bat may fail if msvcp140.dll cannot be found.
Solution: install the x86 Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 from https://support.microsoft.com/en-us/help/2977003/.

· Only Windows 7 x86 and above are supported.
Workarounds involving running inside a virtual machine or separate computer, then modifying the configuration file and proxy settings accordingly may be possible, but I am not able to assist with or debug such setups.

[hiwa29]

Is this Fixer necessary ?
can i use mratio without this patch ?

[anon]

Only one way to know.

[hiwa29]

Only one way to know.

guess i don't need this fixer, mratio didn't give me any error

[bulletproof2k]

@anon Is Ratio and this patch relevant at the moment?

[anon]

Someone already asked that in this very page, three posts above yours.

[charlie333]

The zip file is corrupted

If the SHA-1 hash doesn't match this, then redownload it.

Hi where do I look for these errors, my mRatio runs normally with qbt as client. So should I still use the fixer? Thanks.

[anon]

It seems you're fortunate enough to not need it...

[anon]

Also, preliminary work on v8 has already begun, but there have been so many changes to mitmproxy that just unbreaking existing functionality is going to take a while.

Hi, Anyone able to install this on Mac? I always get the error, "%a is missing Press any key to exit..." when running start.bat as administrator...

[anon]

Unfortunately and as mentioned in the first post, I can only provide support for Windows 7 to 11 (but feedback and potential solutions from others are welcome). mitmproxy has a native Mac version, so in theory you could install that and replicate what the scripts do by hand... but porting a fix for a Windows program running under a compatibility layer on Mac OS has to be the epitome of complication.

My suggestion is to try RatioMaster Plus (should run under Wine if you install .NET 4.8) or BiglyBT Extreme Mod (written in Java and therefore cross-platform).
