This error message is often an indication that LinkFixer Advanced is encountering some permission issue.
LinkFixer Advanced needs to be installed by an Administrator, and we recommend that it be run by an Administrator user as well. LinkFixer Advanced needs to be able to write to the folder “C:\ProgramData\LinkTek\LinkFixer Advanced” as well as the registry, for licensing purposes.
Please re-install LinkFixer Advanced while logged on as an Administrative user. Then, launch LinkFixer Advanced as that same Administrative user.
If that does not resolve the issue, please initiate a support ticket from within LinkFixer Advanced. Details about how to initiate a support ticket can be found here: https://linktek.freshdesk.com/solution/articles/31000126313-how-can-i-initiate-a-support-ticket-from-within-linkfixer-advanced-
