I have developped a SSIS project with 2 packages for SSIS 2012. I stored them in the SSISDB. Everything seems to be correct when I checked under Management Studio. I tried to run my packages with dtexec through stored procedure below and got the error message :
EXEC @returncode=xp_cmdshell'dtexec /SQL "\SSISDB\CLIENT\PAK-SSIS\PAK-Purchases" /SER "SQL01" '
Could not load package "\SSISDB\CLIENT\PAK-SSIS\PAK-Purchases" because of error 0xC0014049.
Description: Cannot find folder "\SSISDB\CLIENT\PAK-SSIS\PAK-Purchases".
