The project settings files are read-only

I have a project, that I last compiled under Quartus II v8.0. I now want to compile it with 8.1 and I keep getting the message:

"The project setting files are read-only and will not be updated with any changes made."

This is stopping me doing anything, because it needs to update things to make it work with 8.1. I have checked the .qsf file and that is NOT read-only. In fact, none of the files in the projects root directory are read-only. What is going on?

Help! Please,

Simon

    do you have a revision control system running on the machine?

    try creating another revision in Quartus and compiling.

    You need to open a cygwin prompt (accessible via the Quartus/bin) directory. Then use cygwin to change the permissions.

    chmod 777 -R *

    Yes, I worked it out in the end. I use a version control system, and made sure that the QSF file was checked out, but still it said they were read-only. In the end I found that not only does it need the QSF file writable it also needs every QIP file writable aswell. Why it needs these when they don't get changed outside of the megawizard I don't know, but that's the case. Version control worked on these with Quartus 8.0 but these days I keep them almost permanently checked out.....
