Thanks for the reply!
Can you please explain this in more details, i use Execution utility for running this packages. so how can i differentiate 2012 and 2008R2 SSIS.
The path. Each install has it's own Tools folder. Search for DTExec.exe on your machine.
So you conclude that we can install 2008r2 on the server where 2012 is installed, if so what precautions should be taken while installing SSIS 2008R2...
If you already have 2012 installed you may be denied installing the 2008 R2 IS service. That I have not tried so could not advise. Worst case you can get the 32-bit version of the 2008 R2 DTExec.exe by installing BIDS from the 2008 R2 media.
