CA Client Automation 14.0 SP2 on Windows 10 / Windows 2016


To repair the machine do this :


1- Start the machine in Safe Mode

2- Open a DOS cmd and enter following commands :

cd "c:\program files (x86)\CA\DSM\bin\AMD64" 

(or cd "c:\program files\CA\DSM\bin\x86" if it is a Windows 32Bits)

rcmirrorinstall -remove

3- Reboot the machine

4- Open a DOS cmd and enter following commands :

cd "c:\program files (x86)\CA\DSM\bin\AMD64" 

(or cd "c:\program files\CA\DSM\bin\x86" if it is a Windows 32Bits)

rcmirrorinstall -install


To solve this problem :

Open a Case at Technical Support to request the fix T5SM172 and T533332

These fixes solve 2 problems :


- Display problem : Screen in blue when a Display Custom Scaling has been set and is greater than 100%

- Crash of Windows at reboot.

Remarks :

For fix T5SM172, CustomScaling parameter should be set to 1 :

ccnfcmda -cmd SetParameterValue -ps itrm/rc/Host/General -pn CustomScaling -v 1


Better Solution : This solution is better than one above.

Open a Case at Technical Support to request the fix T533345 (updated version of fix T5SM179)

With this fix the RC mirror driver is not used anymore. Microsoft Desktop Duplication API (DXGAPI) for screen capture is used.


Additional Information

Please note official patch “SO07736” for Client Automation r14.x provides the ability to automatically use the Microsoft Desktop Duplication API (DXGAPI) for screen capture on Windows 10 and Server 2016. The configuration policy is used to set DXGI for Server 2012 and Windows 8.x. Please see the following for more details:
