Thread:Project:Support desk/Error during install

During installation of the media wiki the script will stop due to several errors. I'm installing in Dutch because the customer wants this. This is the list of errors I got: Database inrichten... afgerond Tabellen aanmaken... Warning: Cannot modify header information - headers already sent in D:\Temporary.004\USBWebserver_v8.5\root\scada\includes\Exception.php on line 269

Warning: Cannot modify header information - headers already sent in D:\Temporary.004\USBWebserver_v8.5\root\scada\includes\Exception.php on line 270

Warning: Cannot modify header information - headers already sent in D:\Temporary.004\USBWebserver_v8.5\root\scada\includes\Exception.php on line 229 Er is een syntaxisfout in het databaseverzoek opgetreden. Mogelijk zit er een fout in de software. Het laatste verzoek aan de database was: CREATE INDEX job_cmd_token_id ON `job` (job_cmd,job_token,job_id) vanuit de functie "DatabaseBase::sourceFile( D:\Temporary.004\USBWebserver_v8.5\root\scada/maintenance/tables.sql )". De database gaf de volgende foutmelding "7: Error on rename of '.\wiki_wincc\job.frm' to '.\wiki_wincc\#sql2-184c-1d.frm' (Errcode: 17) (localhost)". Backtrace:

Does anybody know on how to solve these?
