Hello
I had been unable to play with any of the versions of Bright at my PC with Windows XP. Neither at Arena or at Winboard with polyglot.
Inmediately after executing Bright, exit from the GUI. I tried tp play at the console GUI but is the same. I think my path to the egbb tablebases is OK.
Maybe I am doing something bad or the Bright.ini file is not well configurated by me.
Any help will be welcome.
Regards,
Pablo Urzua

Pablo,

All my pc here (old and new) have no problems with Bright. Even without the egbb (or putting the wrong path of egbb), Bright should run ok on any pc. It's a MingW32 build but packed by UPX! There could be other causes as most WinXP users I know had no problems with these engines.Test w/o egbb support to verify if its the egbb that's causing the problem. Incompatible egmprobe and bitbases are common causes of crashes. In my old Celeron with Win2K, Bright will crash and register an application error dialog box when I mix the new egmprobe (egbbdll.dll) with the old bitbases.

The only other possible problem could be your Visual C runtime dll/s (msvcrtdll.dll???, etc..). It's in the 'VCREDIST' package at microsoft site. Better verify first before installing this package, as I sometimes don't trust microsoft updates/bundled installers. It may add more to the problem and uninstalling is a burden!

If you still have problems, just send me a note. I have unpacked the pure MingW binary. You might give it a try after I fixed my main pc - on maintenance at the moment. I'm using my old one while browsing!

Do you by chance use either new bitbases with an older dll or vice versa?

Hello Guenther,
Another clue; if I do noy indicate the egbb folder Bright works OK.
I use old bitbases (june2006) with new .dll file (March2009).
Best,
Pablo

Hello Mike,
Meanwhile I discovered something is wrong with Bright.ini and my egbb tablebases. If I do not indicate the path at the Bright.ini, the engine works OK included at Winboard with polyglot.ini configurated with the path to the egbb tablebases.
Cheers,
Pablo

IIRC is exactly what _should not work_ as it is the 'vice versa' case
from my above post. You should use the old dll or use the new bitbases
together with the new dll.

Hi Gabor,
Thanks for you reply. I compare you Bright.ini with mine and are the same except for the egbb path.
Meanwhile G.Simon gave me the tip that if I have the old bitbases and the new egbbdll.dll or viceversa
Bright will not work ???. I check my egbb folder and I found that I have old egbb files and the new egbbdll.dll, so I change the new egbbdll.dll file for the old one and !!!!albricias!!! Bright works fine.
Misteries of computation!!!
Best regards and thanks,
Pablo
