Here's what the Handbook tells us:
"Please note that the Software Manager works based on approximations, this means the list can contain some number of errors, for example the software's Main Executable information or the Installation Date might not show the correct data on all software. This is normal. Also, it's not always possible for the Software Manager to detect e.g. The Installation Path of the software, in such case an “N/A” is shown.
Because of this, the Uninstall button doesn't use the extracted information (such as the Installation Path) without asking a permission from you. If you wish to remove all traces of the software you must use the Custom Uninstall feature."
and further on => this warning:
"Warnings: Always remember to validate the given information about the software, that is: the author of the software, the name of the software, its installation path and the location of its main executable. If any of these information is wrong the tool might list entries not related to the software in question, removing these entries could be dangerous. If you are unsure about e.g. the software's installation path, just leave the box empty. Also, using this tool to detect entries of software with a very generic name (e.g. “System”, “Browser”, “Icon” etc) can be dangerous."
