Installation Error / PHP

[Thiede]

After installing the Insiht Manager 7 i get PHP Errors.
Maybe because there is PHP Version5 installed on the same PC.
Is it possible to use PHP5 with Insight Manager 7 ?

Here the Error Message:

Application popup: Warning : Unknown(): (null): Unable to initialize module
Module compiled with module API=20041030, debug=0, thread-safety=1
PHP compiled with module API=20020429, debug=0, thread-safety=1
These options need to match

Thanks
