On our SQL Server 2008 SP1. This error will come up when debugging a converted SSIS package from 32 bit to 64 bit solution:
Warning: Cannot debug script tasks when running under the 64 bit version of the Integration Services runtime.
Here’s the Solution to fix this issue:
In the SSIS Property Pages (#1), in the “Configuration properties” under “Debugging (#2) > Debug Options”, you need to change the “Run64bitRuntime” (#3) from “TRUE” to “FALSE”(#4).
Then, next time run rebuild and use the debugger, it will work.
