The Verba Recording System installer stops with "Failed to create user due to invalid password." message before finishing the installation process.
This error is caused by a conflicting SQL Server user password policy. In case you increase the strength of your password policy after setting a weaker password for an SQL user, the effected user might have access control problems during Verba installation.
Please modify the password of the effected SQL user. Increase the strength of the password according to your current policy (length, small and capital letters, numbers, symbols etc.).
After the SQL user password is updated, you can try again the Verba installation.
