I get the following entries in the log file: >> 2009-09-22 14:10:21, DEBUG : Unable to match uninstall key with regular expression: Unerwarteter Quantifizierer 2009-09-22 14:10:21, DEBUG : Uninstall entry 'Notepad++' matches string 'Notepad++'. 2009-09-22 14:10:21, DEBUG : Uninstall entry for Notepad++ was found: test successful << --- Stefan |
