Originally had Talend Data Preparation 0.1 Beta and I was attempting to upgrade to "M11" version. I deleted C:\Users\\talend\dataprep\logs\app.log on Windows, then installed the following: opensourceetl.net/talend/talendinc/dataprep_10m11/
However, I get a "Java Exception has occurred" error upon application execution. TDP 0.1 Beta ran without issue.
Fixes? Already tried full uninstall and reinstall as well, which took me through some steps, automatically downloaded/installed java, and restarted my computer without prompt. TDP will still not launch when clicked on, so issue has regressed since attempted reinstallation.
