Thanks

It has been known for a while that istalling the new version on top of older may (not definitely will, but may) cause problems, especially with indicators and add-ons.
If you have no custom indicators that you need to back up, we recommentd, if possible, to uninstall properly.
Use the Control Panel->Add/Remove programs to uninstall the existing version. Do not remove the database.
The studies and add-ons that have been compiled and added to MultiCharts are stored in \Program Files\TS Support\PLEditorWhat is the procedure to back up and restore to the new installation indicators addons etc? If there is the slightest risk of problems I would rather 'do it by the book'.

in files named graph.bin and graph_backup.xml
So when reinstalling, you can copy those files to a safe place for backup and then back to that folder, overwriting the existing ones.
