anyone successfuly installed OrCAD Capture CIS 16.6 with CIP?

I am assuming that you are speaking from generic experiance with upgrading OrCAD and have not actually done the 16.6 one.
We have copied the appropriate lines in the Capture.ini file. 

Our Channel Partner is also being stumped by this one so far.  That is why I was asking if anyone has actually done it or seen this issue.  Just trying to open up another channel of knowledge.

Yes, and no, this configuration is fundamental to CIS, CIP just rides on the back of this. Just copying the Capture.ini file might not be too great an idea since the contents do change from version to version. From my standpoint, I would delete the Capture.ini from the new 16.6 location and let Capture rebuild a default, close Capture down, then copy the [Part Library Directories] section from the previous (16.3) Capture.ini and paste those entries into the newly created Capture.ini file for 16.6.

We are running CIP-E 4.002.0015 and "this just works" with our 16.6 installation.

OK, if you are running CIP 4.3, 4.003.0002, it seems to default to the "old" INI file location within the product installation. When Capture starts, check the INI file location that gets written to the session log, for now, this is the INI file that you need to get configured for your libraries. I guess that an update to CIP will be issued to get the 16.6 INI file locations supported.

Update: Too many chefs at the pot! The user "hacked" a 16.5 shortcut to reference 16.6, as a consequence, this picked up the INI file from the installation since the shortcut had a "-i <INI file in the installation>" switch. Therefore, I don't believe that there are any issues in this regard with the CIP installations, apologies to the EMA folks for any implied failing on their part.

I had this same problem and was led to this thread from a google search. This line "this is now stored at %HOME%\cdssetup\OrCAD_Capture\16.6.0 Close Capture CIS while you make the changes to the INI file." in the quoted post was exactly what I needed. However, I was confused by the %HOME% part of that file location and still had the same problem. So, if anyone else comes across this and is confused as I was, %HOME% in my case was "C:\SPB_Data\". Then, the rest of olymouldy's post is exactly correct.

So, to sum up: (in my case) my capture.ini file was located here: "C:\SPB_Data\cdssetup\OrCAD_Capture\16.6.0"

Hope this helps anyone else who may have seen olymouldy's post but was still slightly confused.
