Hi p4spares,
The ‘read-only’ FXT file option has been tested on Windows 7 and the files are being correctly flagged. Will need some further information about what you are checking to get your result
With regard to the launcher, there seems to be an issue with some Windows 7 users having problems. Further investigation will be required. If v0.7 works fine for you, you may need to revert back. Note there have been no changes to the launcher between 0.7 and 0.8, so the issue seems specific to Windows 7.
Will let you know when there is further information on this.
Regards
