Cannot install 4.0

Post by Zoran565 » Mon 02 Apr 2007 15:27


I uninstalled v3 using Add/Remove programs, and then scanned the whole C drive for sdac*.* and dacvcl*.* and deleted them. I even scanned the registry for 'sdac' and deleted couple of entries.

V4 install gives me this error: 'Setup has detected already installed DAC packages which are incompatible with current version. Please uninstall DAC products'.

V4 was downloaded from registered users page 1 hour ago.

What do I do?

Please make sure you have no other DAC products installed.
The product compatibility is provided for current build only.
In other words, if you upgrade either of the installed products it may conflict with older builds of another ones.
In order to continue using products simultaneously you should upgrade all of them at the same time.
