Re: SDFtool Flasher
The storage available on the forum for posting photos & files is very limited and it is usually full and doesn't work, as it didn't for you.
Your best bet is to put a photo somewhere on the internet (https://imgur.com works well for example) and post a link here.

Re: SDFtool Flasher
I am getting the same error. It looks to me from reading everything that MakeMKV used have sdftool64.exe included, which the SDFTool Flasher looks for when starting up. Without it in the MakeMKV directory, it will not start up correctly. Is there a current work around, or an ETD for updated tool?

Re: SDFtool Flasher
Which version of SDFtool Flasher are you using? The latter versions should all include .NET runtimes so that you don't have to install it yourself.Cthulhu wrote: Thu Sep 24, 2026 5:51 pmThis is exactly the same one Im getting thanks for posting a screenshot of itwilly wrote: Thu Sep 24, 2026 5:40 pm Here is the link to the screenshot of the error message I received.

Thank you ,dcoke22, for this information.
Also, ensure you have MakeMKV installed in the default location ('C:\Program Files (x86)\MakeMKV)
Cheers
