Hi,  
While setting up the SW6.4.18.1 on my localhost via the MAMP, I am getting the following error on the step Configuration:  
An exception occurred while executing ‚INSERT INTO sales\_channel\_domain (id, sales\_channel\_id, language\_id, url, currency\_id, snippet\_set\_id, custom\_fields, created\_at, updated\_at)

Any clue how I can fix this or what I am doing wrong?

Looks like your database was already in use before. Consider ditching this database and creating a new one. I also found this: [magento - SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1922-1' for key 'IDX\_STOCK\_PRODUCT' - Stack Overflow](https://stackoverflow.com/questions/10044062/sqlstate23000-integrity-constraint-violation-1062-duplicate-entry-1922-1-f)
