failed installation

[dinpcven]

hello

I am trying to get a cmssimple to work on my windows 2000 server, IIS, php 511, mySql5.0 but it fails during installation.

I get this error:

Warning: NewDataDictionary(f:\websites\pcven.dk\sider\cmsmadesimple\lib\adodb_lite/adodbSQL_drivers/sqlitepo/sqlitepo_datadict.inc) [function.NewDataDictionary]: failed to open stream: No such file or directory in f:\websites\pcven.dk\sider\cmsmadesimple\lib\adodb_lite\adodb.inc.php on line 158

Fatal error: Class 'ADODB2_sqlitepo' not found in f:\websites\pcven.dk\sider\cmsmadesimple\lib\adodb_lite\adodb.inc.php on line 161

any ideas?
