Hi,
I'm running D7 with Vista. All seems to work after some initials problems (I did the upgrade from XP).
But I always get Incorrect MDAC version. I installed the latest MDAC but that didn't make it work. I had to change OLEDBAccess to make it work:
I changed this line:
if FProviderPrimaryVer < 7 then
DatabaseError(SWrongMDACVer);
into
if FProviderPrimaryVer < 6 then
DatabaseError(SWrongMDACVer);
Because with Vista FProviderPrimaryVer is equal to 6. Probably not the best solution but works for me.
