When I run it, the following message appears.
-----------------------------
Error loading blkindex.dat
-----------------------------
and is terminated.
The same symptom of erasing previous versions and installing new ones.
What is the problem? I need help.
You need to delete the old database.
Go to your \ bzlcoin folder and delete everything inside except wallet.dat.
WARNING, if you delete wallet.dat, you lose access to all your coins.
If you need more help access the forum: forum.bzlcoin.org or the Telegran group
