typo3 7 LTS installation database query failed

Question

I get following message when trying to first install the typo3 7.6 LTS version .

I have tried several new databases, they are all empty and I still keep getting this error :

**Error:
Duplicate entry '1' for key 'PRIMARY'**

Answer 1

You could try to empty that table by hand and execute the shown sql query by hand. Maybe you can identify the error.

You also should compare the definition of the table in question.

maybe your mysql(?) has some problems creating the tables as expected.

Answer 2

I was able to access the backend by calling the URL, even without making it to step5 (100%) the backend opens up. Step 4/5 would reload and redirect so I tried logging into the backend without finishing to the last step. It seems to work.
