    Controlled Folder Access


    Hi.

    I've been using Controlled Folder Access recently but I'm having a problem getting one application to change/create files. I use doPDF8 to create PDF files, but when CFA is active, it won't save my work. The notice explaining that something has tried accessing the folder only comes up once. (I assume that if you don't do anything about it, the program trying to access the file is put on the 'black list'.) Turning CFA off and then on again causes the notice to appear once more. However, the notice seems to suggest that it is C:\Windows\splwow64.exe that is trying to access/create the file, but when I put this into the 'allow app control' list, it still doesn't work. The only way I can find to get the PDF file created is to turn off CFA, create the file and then turn it back on again.

    Any ideas?

    Splwow64 is system print driver host.

    Did you try to add dopdf to allowed apps? Other solutions would be to print via Windows pdf printer, or save file temporary to other location (non controlled).

    Controlled folders access doesn't work via blacklisting, but rather whitelisting. Only allowed apps can access certain folders.

    Hi AndreTen.

    I don't know the location of the doPDF driver/app; I can't seem to find it. I would definitely want to use doPDF rather than WinPDF.

    This should be automatic anyway. Uninstall it and reinstall newest version.
    download it from their site, Softpedia or MajorGeeks - other sites could add some unwanted programs

    Edit: no need to reinstall. Look the post below

    Ok, made a simple test, and printing with Dopdf in controlled folders is dependent on the application you are printing from. Dopdf is simply a driver , and app (like Word or Firefox) must have approved access to your folders.


    From which app are you trying to print?

    1709 is very old. The functioning of Controlled Folder Access has changed little since then but the UI has improve enormously. In 1903 it now tells you exactly what was blocked and allows you to add it to the list of allowed apps with a single click. With 1709 you have to dig deep into the Event log to find out the path and name of the executable you'll need to allow through CFA.

    Open Event Viewer, go to Application & Service Logs > Microsoft > Windows > Windows Defender > Operational. Look for Event ID 1123 which will give the full name and path of the executable that was blocked. IDs 1125 and 1127 may also be relevant.

    Note that a restart is required before any apps you have added will be allowed through CFA.

    AndreTen: Thanks. All of the word processors I use have this problem: Word, Ableword, Open/Libra Writer, etc.

    Bree: Thanks. Yes, I know it's old. Unfortunately (at the time) I had a problem with the updating. Windows refused to update itself and (I believe on this forum, as with others) no one could come up with a good way to help me, other than a clean install, which I didn't want to do. Defender seems to update regularly, but nothing else. Sooner or later there may be a problem, but at the moment it's fine.

    Until you get the update to work the event viewer is the best way to find the path and name of the file than needs to be allowed through CFA. It's not always an obvious one, for your LibreOffice it is soffice.bin, for example.

    Matt316, can you please, for testing purposes try to print something with Microsoft pdf printer? If you don't have it installed, it is available from Control panel / Programs and fetures / Turn Windows features on...

    Just curious...

    And what did you already do to upgrade to 1909, or 1903?
