Invalid CAM uri

Product:
Cognos TM1 10.2.2
Microsoft Windows 2012 R2 standard server

Problem:
When inside TM1 architect try to add a new user (clients – add new client) you get a error message about the CAM. The dialog will not show up.

Possible solution:
The value in the file tm1p.ini for that user is not updated with a URL to the cognos bi server.

You update the TM1S.CFG file for the TM1 server – but this change is not copied to the TM1 architect users.

IntegratedSecurityMode=2
ServerCAMURI=http://biservername:9300/p2pd/servlet/dispatch
ClientCAMURI=http://biservername.domain.com:80/ibmcognos/cgi-bin/cognosisapi.dll
ClientPingCAMPassport=900
CAMPortalVariableFile=portal\variables_TM1.xml

Only new TM1 architect users will get value from file E:\Program Files\ibm\cognos\tm1_64\bin64\tm1p.ini.

You need to close TM1 architect and update this file
C:\Users\%username%\AppData\Roaming\Applix\TM1\tm1p.ini in notepad.

Add values for
AllowImportCAMClients = T
CognosGatewayURI = http://biservername.domain.com:80/ibmcognos/cgi-bin/cognosisapi.dll

save the tm1p.ini file and start the TM1 architect program again.
