Error: " Your preferences file cannot be read...etc.."

  • I searched for a fix and found out that the problem arises when one is using the true Administrator account, and I am..
    But It is important for me to use this account because of the privileges..
    I would like to learn a fix for that issue while still using and maintaining my preferences file..
    Thank you for your consideration guys...

    Edit: BTW I am using portable Opera

  • BTW I am using portable Opera

    By "portable", do you mean the "standalone installation" in Opera's installer options (that "Opera USB" at uses) or do you mean the Opera package from

    @sgunhouse, I think you've mentioned this issue before. Do you know how to work around it and does it affect standalone installations too?

  • I mentioned it as a possible cause, the only time I've seen it myself was some time ago when trying to reopen Opera immediately after closing it (which is to say, the files were still considered "in use") and waiting a few seconds longer before reopening solved the issue.

  • Hmm, if you right-click on "C:\Users\Administrator\AppData\Roaming\Opera Software\Opera Stable" and goto "properties", what does it say for permissions on the security tab. Maybe explicitly add the Administrator account to have full control instead of just the Administrators group. Might have to do something similar with "C:\Users\Administrator\AppData\Local\Opera Software\Opera Stable".

    Also, if you can find this issue for Chrome when searching Google, the fix might work for Opera too.
