TP crash during install

[Henk]

Installation of SMF V1.1.2 = OK!! Up and running
Installation of TP V0.9.8 = BAD... no errors during installation
After install the following messages:
Warning: main(): Unable to access /home/httpd/vhosts/brussenalmere.nl/httpdocs/Sources/TPortal.php in /home/httpd/vhosts/brussenalmere.nl/httpdocs/index.php on line 55

Result: No forum!!
What is wrong?

Have three more forums up and running without these messages!
I am out of ideas after four re-installs!
