Question Installation interrupt with the following error

but please tell me before you are deleting or changing some big stuff

I've nothing changed but seen the error message. You need a repair via ftp. Here is the solution (German language should not be a problem for you).

For all other users:
If you have a error message such as
Table 'DB2740107.#__kunena_configuration' doesn't exist SQL=SELECT * FROM #__kunena_configuration WHERE id=1
It seems, this is caused by a erroneous Joomla file when Joomla is installed via AppWizard (such as at Strato).

This could be a solution:
Download Joomla and unzip it. Upload all files (without the install folder) via FTP on your page. Then install Kunena again.
Important! Create a full backup previously.

seriously? this is a mess, the hoster and the webpackage from him is the Problem, nice.
but thank you a lot for your Kind Support ! i will try this when im back home, and write then again here

This database error occurs very rarely and was resolved so far only by this solution. But I've edited my message above now.

soory ist me again, i tried the complete Weekend many times, upload joomla files and and and , but still plugin Installation failed.

no further ideas ? i dont know what can i do
