Hi guys, trying to us the system.util.retarget (“Project”,[“SomeWindowPath”]) with 8.0.16 and it keeps erroring out saying “Error Launching application: HttpResponseException: 404: Notfound” I tried the script without the window path and it opens fine. I copied the window path right out of the 8.0.16 designer. has something changed with the naming of window paths I did not know? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/1/21c3bbdf000aab1003b4303ff2c9a610df2c1969.png) Just to clarify, the project name or window paths have not changed. I imported my 7.9.12 in and upgraded the whole thing to 8.0.16 so there should be no naming problems. Thanks ---

In the script where you’re calling `system.util.retarget`, are you specifying the other gateway address with `/main` at the end? If so, try removing that `/main`. ---

Hi Paul, I did see that in other topics users put on here. no in this case this project resides on the same gateway as the source project. I even tried to put the address of the same project in just for fun and still no luck. ---

Ah, didn’t read your message closely enough. Is the project you’re trying to retarget to an inheritable project, by any chance? ---

it is not. all my projects are on their own. both destination project and source project are enabled and none of them are inheritable. again, weird thing is if I put just the project name, it goes in fine. The moment I put a window path, it doesn’t like it. ---

can you post the script line for retargeting? are you using keyword arguments for the script? ---

Hi J, In 7.9.12 I was using system.util.retarget(“Audits”, None, None, [“Shipping/OB\_Shipping/Outbound Shipping”]) in 8.0.16 I changed it to system.util.retarget(“Audits”, [“Shipping/OB\_Shipping/Outbound Shipping”]) Since it did not like the None’s ---

you could change it to this: `system.util.retarget("Audits", windows=["Shipping/OB_Shipping/Outbound Shipping"])` which i would expect to work The reason for this is the 2nd arg (when not using [keyword arguments](https://docs.inductiveautomation.com/display/DOC79/User+Defined+Functions#UserDefinedFunctions-KeywordArguments)) is expected to be a Gateway Address or list of addresses, so the retarget function is looking for a gateway at `"Shipping/OB_Shipping/Outbound Shipping"` which will obviously fail. ---

Thanks, the window=[] did work.
