Default Prime95 resetting LL test

Strange one - the last couple of times that I've booted my computer, Prime95 has decided to restart the LL test I'm on at the moment from the beginning, losing a couple of weeks' worth of processing in the process. I'm using version 24.14 on an Athlon running XP. Can't see anything odd in the results file either. Any ideas?

File permissions? (Right click on icons to select properties and turn off "read only".)

File permissions on which files?

The directory that contains Prime95 needs write permission (if that is settable in Windows.) The prime95 can be "read only" and any associated readme/help files. Initialization files (e.g. prime95.ini) along with log files and save files must not be "read only".

(I use LLR under linux and have little knowledge of prime95.exe under windoze.)

Preservation of file permissions when backing up to CD is a common problem. I use zip to get around this even though a corrupted zip can be hell. If I recall correctly the CD burning software I use has an option to preserve file permissions.

If you are running Vista the whole directory Program Files is read only for most users. If so you should change the premissions on the "\program Files\Prime95" directory so as give users write access.

Stated XP in the OP. Anyway, it seems as if the whole directory became read only somehow. I'll see if that fixes it upon a reboot.

This is common enough of a problem, maybe a sticky thread?

George, could you tweak the current in-dev version of your code so that it reports these kinds of file-permissions problems to the output window? That way users wouldn't be blindly poking around, trying to figure out what's causing the problem.

Also maybe see if a savefile *exists* (whether read-only or writeable) and report-problem/quit if it's found to be read-only, so the user can change the permissions and not lose their work by having the file blown away.

You may as well just have the program attempt to reset the file permissions itself too since it'll likely be running a from an account with the access to do so. [the same account the removed the permissions in the first place]

No it didn't, the directory keeps setting itself back to read only no matter how many times I turn it off.

Have you tried setting the read only attribute both on the left hand (tree) pane and right hand (icon) pane of windows explorer?

Does the advanced button give anything interesting in "properties"?

Did you install Prime95 under your account (or administrator)?

I am really out of my depth with this problem.
