For a few days now I have had no way to add new printers with my Windows 7 Home Premium laptop under "Start", "Devices and Printers". I've been trying a lot for days, everything doesn't help anymore.
The following constantly appears: "Add printer" can't be opened. Access denied
The printer is a fairly current Brother DCP-J4120DW Wi-Fi printer, it was also connected to the laptop shortly before. It was printed and also scanned. Only after I stupidly, on the same evening, under the properties of the printer, via the tab Security and Permissions at EVERYONE, have denied some accesses, i.e. Have correctly ticked the box Denied, can I no longer get this printer connected to the laptop. There's no scan and no more printing. Removing the printer and trying the installation again did nothing.
Currently I only get the above-mentioned notification with access denied. I'm logged in as admin, there are no other accounts. Trying through the registry editor to give every user full access does not help either. The same message always comes.
What have I done or changed so seriously? Hope you can help, I'm not an IT professional.
Start the computer in safe mode. After switching on, immediately press the F8 key.
Remove the checkmarks in the Control Panel for security and permissions.
Or you can start System Restore from an earlier restore point.
