On 9-27-2011, Cat 11.10 Preview has finally fixed the Dcom error at shutdown. On 9-28-2011, Cat 11.9 WHQL Release Notes indicates that the Dcom Errors are fixed. Is anyone getting this error after install cat 11.4? I'm reading a few reports of this and wanted to know if anyone else noticed this? You can check this by opening up event viewer and looking at Administrative Events. Update: Problem is reproduced after a reboot or shutdown. Error appears to only show up during shutdown process. Using a driver earlier then 11.4 March 22/23 preview solves the problem. Cat 11.4 March 7 preview and Cat 11.3 don't exhibit that error. Disabling atiesrxx.exe (AMD External Events Utility) may stop the error from happening when shutting down. However, may cause other problems that effect 2D/3D clocks of your video card (or causes another event viewer error). 11.4 (Early) Preview - March 7th [8.84.3-110226a-114256E] *No DCOM error* 11.3 WHQL [8.831.2-110308a-115928C] *No DCOM error* 11.4 Preview - March 23rd (posted on March 29th) [8.84.2-110321a-115519E] *DCOM error* 11.4 WHQL [8.841-110405a-116954C] *DCOM error* 11.4 Hotfix -April 27th [8.84.9-110427a-118103E] *DCOM error* Cat Beta 8.85 released May 5, 2011 (8.85-110419a-116502C) *DCOM error 11.4c new hotfix dated May 4, 2011...waiting for release 11.5 released May 9, 2010 *DCOM error* 11.5a Hotfix released May 9, 2010 *DCOM error* 11.5b Hotfix released May 25, 2010 *DCOM error* Cat Beta 8.86 released June 3, 2011 *DCom error* 11.6 WHQL June 15, 2011 *DCOM error* 11.7 Early Build June 29, 2011 *DCOM error* 11.7 WHQL July 27, 2011 *DCOM error* 11.8 Preview July 27, 2011 *DCOM error* 11.8 WHQL, August 17, 2011 *DCOM error per GPUCoder 11.10 Preview September 26-27, 2011 *DCOM Fixed, Finally* 11.9 WHQL September 28, 2011 The release notes indicate that this drivers fixes the Dcom issues. Thanks to k1net1cs for checking some of the drivers. Edit: A temporary solution is to go to services and select AMD External Event Utility stop the service and set it from automatic to manual. Then reboot the PC (not just to see if the Dcom error comes up or not but to start windows with the service disabled). Once done you should be able to play games and the 2D and 3D clocks should work as normal. CCC should also work as normal. Just keep in mind that you had the service disabled if you run into any problems when you install different drivers. This is by no means a fix nor is it a solution but a temporary change until AMD fixes the problem. Edit #2: After some searching around I found a few threads discussing the issue: http://www.rage3d.com/board/showthread.php?t=33976892 http://social.technet.microsoft.com...l/thread/10e6ca24-8fe4-4b7f-82e7-154f0957935d http://forums.amd.com/game/messageview.cfm?catid=279&threadid=150420 http://forums.guru3d.com/showpost.php?p=3967469&postcount=48 http://www.computerbase.de/forum/showthread.php?t=891838 http://forum.radeon.ru/viewtopic.php?p=750925 http://forums.amd.com/game/messageview.cfm?catid=354&threadid=119657 http://www.rage3d.com/board/showthread.php?t=33977542 New Update: You can use atiesrxx.exe and atieclxx.exe files from Cat 11.4 Preview March 7 in place of the current build version (Cat 11.7 for example) to prevent the dcom error. However, this may cause other problems. -Start it to decompress the files. Once you see the welcome screen exit. You are not doing an full install. -Navigate to C:\AMD\AMD_Catalyst_11.4_Preview_Win7_March7\Packages\Drivers\Display\W7_INF or W76A_INF\B114386\. I think W7_INF is for 32bit but I'm not sure. -Copy atiesrxx.ex_ and atieclxx.ex_ -Create a Temp Folder on your hard drive, example C:\temp -Type CMD at Start's search box and start it with Admin rights -Navigate to that folder, example: cd\temp -Type: expand atiesrxx.ex_ atiesrxx.exe -Type: expand atieclxx.ex_ atieclxx.exe -Open Services and Disable AMD External Events Utility then stop the process -Navigate to windows\System32\ and place atiesrxx and atieclxx in another folder (don't delete) -Replace them with the same files from Cat 11.4 Preview from the Temp folder. -Set AMD External Events Utility from Disabled to Automatic. Then start the service -Reboot. Once you do the dcom errors should stop. However, there maybe stability issues or other problems using the older atiesrxx and atieclxx. I don't know how stable those older files are on current Cat releases. If you experience issues just disable and stop the AMD External Event Utility and replace the files found in system32 with the originals. Then set the AMD External Events Utility to automatic and start. You do this at your own risk. Edit Update: If you use this method and want to uninstall your current cat drivers for a different version just switch the old files with the original ones 1st before uninstalling. Edit Update: After using this for a week or so I've experienced no ill effects in games, streaming, etc. Caution is still advised though. Update: After using this method for over a month I've not seen any ill effects. Gaming, watching videos, recoding movies, etc have all worked without issue. New Update: Cat 11.10 Preview has finally fixed the Dcom errors (at shutdown) that has been an issue for the past few months. If you are reading this post you no longer need to use the old Cat 11.4 Preview's atiesrxx and atieclxx files. One More Update OP updated to reflect the release of Cat 11.19 released 9-28-2011. The release notes reflect that the Dcom issue is fixed.
