How to download Multibit Classic? Or how can I unencrypt .key file without it?

[kodiak1120]

I have an old multibit.key file that I'm trying to import into Electrum.  The text file has +'s and ='s, which I understand means it was encrypted by Multibit, thus I cannot just import it into Electrum without unencrypting it first.  How can I do that?  I understand that if I download Multibit Classic, I can use that, but I can't find it anywhere reliable.  Can it be downloaded here?  https://github.com/Multibit-Legacy/multibit  If so, how do I download it for Windows? 

Alternatively, is there a way to unencrypt it without using Multibit Classic? 

Thanks.

They removed the binaries but you can compile it yourself.

Thanks.

HCP did a pretty detailed writeup earlier[1], might want to refer to that.

The guide that I wrote earlier as linked by ranochigo above is your best bet without Multibit Classic.

I will just add that unless you know what password was used to encrypt that .key file (and/or have a very good idea of the length of the password and whether it was UPPER/lower/numbers/symbols etc) then your chances of decrypting that .key are virtually zero.
