Hi @jacklezz sorry for interrupting you, but I tried again to install the latest version in windows 7 ultimate, but I got the stopped working popup message again, I already install the latest visual ++c from microsoft, but got this error again..
You could try to do the following: Backup the whole installation folder and then Delete the blocks, sporks, zerocoin and chainstate folders (or all except bin and backups) and all the .dat files except for wallet.dat to let it resync from scratch. If your computer shuts down unexpectedly while running any Bitcoin-based Core wallet or for some reason you didn't exit the app safely, sometimes such a thing is required.
If that doesn't help, you can try to restore one of the newer wallet.dat backups in the backups folder. (Overwriting the wallet.dat in the main folder).
Also in the future when switching from one version to another, just use the .zip file to copy the executables instead of the installer/setup .exe.
You may also try our
latest version 2.1.2 that is now up for open testing in our Github, but has not been officially released yet.
