Interesting. That screenshot is just of the files named wallet. All the other files are still in their proper directories. It's just the application is so old it refuses to run. I guess if the wallet was stored in some sort of temp or roaming directory it is long gone then.

I also have a 2nd wallet that is even older (2011), but I have less hope of recovering anything from that than the 2015. The wallet files are all .h or .cpp.

I get this error when I try to rename the exe to add -reindex.

Okay I was successfully able to install Bitcoin Core version 19.0.1

However, it is syncing with the network and is 12 years behind. I do not think I have enough space on my hard drive to complete the sync. Last time it took up like 900 GB when I tried a year ago.


While it's syncing I looked to see if there was any options in the settings to import my old backup_wallet.dat file and I don't see anything.

I looked in the bitcoin folder and I did not see a debug log.
Could you explain the -reindex or link to a topic that covers it?

I don't have space on the hard drive to run a full node.
I downloaded bitcoin core v 22.0. I'm not sure what version was on the laptop from 2015, but it was out of date and could not sync.

Here is the error that pops up within 10 seconds of trying to install the bitcoin core wallet.

Hello,

I have a backup_wallet.dat file from 2015. It was on a laptop using bitcoin core which could not longer sync. So I created a backup and put that file on my new pc running windows 10. I've tried to install the latest bitcoin core program but I get an error when installing.

Error Loading Database
Do you want to rebuild the block database now?
OK/Abort

Both options just close the installer.

Any suggestions on where to go from here? I've read the guides and have only found solutions to people with this error after they have already successfully installed the wallet.
