https://community.qlik.com/t5/Talend-Studio/TOS-Data-Integration-Preview-delimited-files-error/m-p/2279995#M54982 Thanks for that. I can't believe it was that simple! The TOS program was installed in Program Files so there was a space in the path. I re-installed elsewhere and it worked fine.

To help pursue this I am attempting to follow through your on-line tutorials but I seem to have fallen at almost the first hurdle! I'm trying to create an input from a delimited file ( customer_demo5mn.csv file). The data shows OK in the File Viewer but when I try to Preview the file I get the following output: <BR /> <BR />java.lang.NoClassDefFoundError: testproject/shadowfileinputtodelimitedoutput_0_1/ShadowFileInputToDelimitedOutput <BR />Caused by: java.lang.ClassNotFoundException: testproject.shadowfileinputtodelimitedoutput_0_1.ShadowFileInputToDelimitedOutput <BR />at java.net.URLClassLoader$1.run(Unknown Source) <BR />at java.security.AccessController.doPrivileged(Native Method) <BR />at java.net.URLClassLoader.findClass(Unknown Source) <BR />at java.lang.ClassLoader.loadClass(Unknown Source) <BR />at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) <BR />at java.lang.ClassLoader.loadClass(Unknown Source) <BR />Could not find the main class: testproject.shadowfileinputtodelimitedoutput_0_1.ShadowFileInputToDelimitedOutput.
