In WIX project I have an custom action that works on SQL server with some data and in some cases faills.
If I have version 1.0 installed and I want to upgrade to 2.0 and the custom action faill then the rollback is called, but in place of remaing the 1.0 binaries/registry entry/services all data is erased and I have nothing installed.
What I must change that after rollback the version 1.0 to remain installed and working.
