I am developing with “Oracle Data Access Components”, version 5.80.0.42, with Delphi 2006.
My OS is Windows XP Italian version.
After updating Windows, Delphi 2006 crashes while loading the packages. The package causing the error is dclOdac100.bpl. The error windows has caption “bsd.exe – Application error”; the rest of the message (translated from Italian) is “The instruction at 0x18de0054 referenced memory at 0x00000000. The memory could not be written.”
When closing the error message, Delphi is terminated. If I uninstall ODAC, Delphi starts up without any problem.
There aren’t any problems with the other components and everything is working fine – except for these ODAC components.
I also tried to install version 6 trial, getting the same result: Delphi crashes while attempting to load dclOdac100.bpl.
Any suggestion?

Thanks in advance.

There is some attempt that I can make in order to try to resolve this problem?

Please try to uninstall ODAC, search through your computer for dac100.bpl, dacvcl100.bpl, dcldac100.bpl, odac100.bpl, odacvcl100.bpl, dclodac100.bpl files, and remove them if they will be found. Then install ODAC again.

Resolved! The problem was not due to dclOdac100.bpl but was caused by Oratools. After unistalling them Delphi with Odac started without any problem.
