INSTALLING AN APPLICATION (TS DEPLOYMENT TYPE) WITHIN A OS TASK SEQUENCE.

[MarkK]

I recently setup a complex application with 16 dependencies. I have bundled them into a Task sequence and have created a task sequence deployment type. each application dependency is called by a install package step in the task sequence. the package also includes a program that runs the install command line. i was able to deploy the application to an install collection and have successfully installed it on multiple endpoints. I am very happy with the results.

My previous test was simply pushing software to the endpoint (software center) on previously built windows 10 device.

I now have a new challenge..
i would like to image a new machine and add this application to install as part of the OS deployment. this is a common task and I currently utilize this via a Custom Operating system portal URL. (MDT). the problem I am now experiencing is when the application is called to install during the OS task sequence deployment. it immediately fails. I believe it is because i am currently in a TS env. and cannot create another. is there anyway to suppress this ?

currently you can add a task sequence step in a OS task sequence. but this only seems to work if i call " run task sequence step"
