You receive an "Access is denied" error when deploying SSIS packages or when reading objects from data source.
Cause & Resolution
See this article from Microsoft: Integration Services Service (SSIS Service)
This article applies to: timeXtender 4.5, tX2012, TX2014.
The SSIS requirements has not changed. You still need SSIS installed on the deploying machine if you are using SSIS.
In the past I received your feedback that "You need SSIS installed on the deploying machine (Where TX is located)." ...is this still the case ?...or do I understand from this article that you can use remote SSIS also for deploying TX from a server whcih does not have SSIS locally ?
