No i didn't use. I'm not confident with my skills to do that
If you're not confident installing or using Python, then it is going to be difficult to recover your seed. Your only other option would be to trust someone with your seed and get them to recover it for you... obviously this is a "Bad Idea"™ unless you REALLY trust that person, as once they recovered your correct seed, they would have full access to your wallet!
If you need help getting Python installed... I'm sure myself and/or others here will be able to help walk you through it. It really isn't THAT difficult... and the seedrecover.py script is actually a GUI based recovery tool (it has pretty windows!
)
What operating system are you using? Windows? If so... go here and get Python 2.7.14:
https://www.python.org/downloads/release/python-2714/The 64bit version is labelled as "Windows x86-64 MSI installer"
The 32bit version is labelled as "Windows x86 MSI installer"
There are also versions for MacOSX on that page if you're using that operating system.
Do you mean one of the bitcoin address for this wallet? Yes i can find it.
Yes, you need one of the bitcoin addresses generated by your seed... preferably one of the first addresses generated, as it helps speed up the process (script only has to generate a few addresses to check instead of hundreds etc)
