I'm having this problem "[2.250129] [INFO] Setting TAP-Win32 Adapter v9's MTU to 1450 [5.426310] [ERROR] MUDEC_00104: CreateProcess failed (216). [STDERR] Empty file."

I'd added it manually. Sorry for this inconvenience. However this is my first time got reported for MUDEC-00104 error code. Error code 216 means ERROR_EXE_MACHINE_TYPE_MISMATCH:

* This version of %1 is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

Did you change a netsh.exe binary to another one? It failed to execute `C:\Windows\system32\netsh.exe` to set MTU.

I never change this file, actually I did not know it existed
I will check if reinstalling or repairing solves the problem
thank you for your help

Yes please try to run it at Command Problem as Administrator. It might show a error message you saw before. If it's working fine, please let me know.

well... I tried programs like Dll Suite, I updated all drivers with DriverEasy, but the same dialogue box appears everytime when I open the mudfish with the message of incompatibility of the netsh.exe with windows 64 bits
(one question, only curiosity... e.e
I'm talking from Brazil, where you are talking?)

I have no idea what's fundamental issue on your executable file. :-) You can try to use a tool such as Dependency Walker to analyze which DLL is broken.

I'm currently live in California, US now. :-)

Hey loxch :D, I think I managed to solve
If anyone else has this problem
Here's what I did:
- Updated drivers
- Repaired problems with dll through programs for that
- I downloaded the "netsh.exe" 64-bits and 32-bits (I don't now if have any diference)
- Changed the permissions on the folders of my operational system (Windons 7 64 bits) SysWOW64 and System32
- And manually replacing the files in their respective places

but now appeared this issue "mudec_00049", this have anything with my previous problem?
and sorry for my english I never talked in a real conversation before e.e

Wow it seems you're one of power users for Windows. Good to hear. :-) I'll update our official document based on your comment. Thank you for information.
Regarding to MUDEC_00049, I found a problem and fixed your account. Please log out and sign in again to be properly applied. I hope it's gone now.

EDIT: I can understand your english well and it's well formed. :-)

I'm happy to help, but what I did was just a little research
and I think another possible solution would be to reinstall a Windows security update that had an error and I did not realize
Thank you very much for the service and the friendliness :D

Got it and you're welcome. If you have other questions, please let me know. :-)

Hey... :(
I would like to request a refund, because in my ping testing period the ping decreased from 200 to 60, I was very happy,but I not tested enough to see that once in a while a lag spikes occur and are crucial in the League of Legends, unfortunately I can't continue using the program, even though I liked it so much :(
have any way to cancel the purchase?

:-) No problem. I'd refunded it. Thank you for interesting to Mudfish.

I'm very grateful
you and your team are to be congratulated for doing such a good and cheap program
and fulfill the promise of the return of credits
unfortunately it did not work well here :(
until next time :D

Please remember Mudfish and I hope it'll be better than before when you visit here next time. :-)
