ODAC and MYDAC Compatability

Post by wjm4 » Mon 12 Feb 2007 21:33

I have just recently installed the newest version of MYDAC on to my computer (XP, BDS 2006 using the C++ Builder Personality). Now when I try to open a project that uses the ODAC components there is an error that says:
Error Reading Form
Access violation at address 06CA60DB in module
'dac100.bpl'/ Read of address 00000000. Ignore the error
and continue? NOTE: Ignoring the error may cause
components to be deleted or property values to be lost.

If I ignore this problem, all of my query components disappear from the form. Also if I try to open a new VCL Form, I can not put a Query (ODAC) on the form. It gives the same "access violation of dac100.bpl" error.

I have already tried uninstalling both ODAC and MYDAC by the steps found in many topics on the form (There were no traces of either anywhere after install) Then I reinstalled both and the same problem arose.
I have also checked the path (Compiler and Linker) to make sure that all the paths are set correctly and they are for both MYDAC and ODAC.
I have had ODAC installed for a couple of weeks and it has worked fine prior to MYDAC being installed.

Environment Info:
XP Professional sp2
Borland Developer Studio 2006 using the C++ Personality
ODAC Version: 5.80.0.38
MYDAC Version: 4.40.0.22

The last ODAC build is 5.80.0.39. Try to download it and reinstall both MyDAC and ODAC.
