Juan-
I filed a bug report on 651, not knowing which thread for problems with 1.6.9.651, since I have not been able to get the updating to work on my E6400 32-bit laptop (XP SP3). After successfully installing 651, the updating just fails with a blank update log if I run it from my normal login account. If I give it, when it gives me the choice of these two accounts, the administrator account, it still fails with the message given in that post about some other process owning the update log.
I thought 1.6.9 previously was running ok for me on this machine.
Thanks,
-Jeff
