Error: Can't Open project -- Quartus II 6.0

recently encountered many times, previous built project (Quartus II 5.0) can't be opened in Quartus II 6.0, and can't be opened in 5.0 as well.

All files are sitting in the original location, no copy or move operations ever done.

X Error: Can't open project -- you do not have permission to write to all the files or create new files in the project's database directory.

WindowXp, change all files into not READ ONLY, still doesn't work, after trying to open the project, some files automatically return to READ ONLY again.

Please help!

    If anyone finds this later, this is an error with how the attributes are set with the project files. See following link:

    https://www.intel.com/content/www/us/en/support/programmable/articles/000084612.html

    To solve this:

    1. Open a command shell (Start menu -> Run... -> Enter cmd and press OK).

    2. Change to the project directory, i.e. cd <project path> and press Enter.

    3. Run the one of the following commands:

    attrib -R /S /D *

    This should clear the write protection flags for all the files and subdirectories in this project direcotry.

    It is not necessary to delete or reinstall any files or directories.
