Installation-Error: Error in my_thread_global_end(): 2 threads didn't exit

[rsgsxf]

Hi folks,

 

when trying to install I directly on the first page get the following error:

Error in my_thread_global_end(): 2 threads didn't exit

 

If I nevertheless click to continue after I accepted the disclaimer,

the system-compatibility shows "okay".

 

Next page the database-check will not work, even if I already have

created a MySQL-Database called prestashop ...

 

The error-message (shown above) always is seen at the bottom, left corner.

 

Who can help ????

 

Answers in english or german language are highly appreciated :-)
