SSIS Not Executing any Script Task
I spend the day dealing with the same problem in vain, my temporal solution would be to run the SSIS package with a CMD command.

here is my example:

dtexec /ISSERVER "\"\SSISDB\project_____name\Main_Package.dtsx\"" /SERVER server___name /X86 /Par "\"$Project::var___name\"";"\"value___value\""
