Thanks for helping to keep the price high until I can get my old coins out of cold storage. The wallet.dat file is incompatible with the new version so I am having a difficult time accessing them. Any ideas?
What version do you need?
What year was it released in, was it 2011 or earlier?
I notice the old version qt binary downloads have been removed from sourceforge.
Pywallet is supposed to be good for extracting keys from wallet.dat files, but you need to install python to use it.
http://sourceforge.net/projects/pywallet/files/There is also source code for old qt versions on github, but it needs compiling.
