Catalyst Control Centre: Host application has stopped working

"Catalyst Control Centre: Host application has stopped working" mean and how do I fix it??

This may be the solution you are seeking.

I recently removed the Vista Recovery Center malware from another one of our company laptops. It has ATI graphics installed. This malware hides most of the files on the PC in an attempt to fool you into thinking that your PC is really damaged like it is reporting. Removing the malware does not undo the hidden aspects. In Vista, the c:\Users*"your profile name (usually Owner)"*  folder contains the AppData subdirectory that the Catalyst Control Center needs to access in order to function. When this directory is hidden, then CCC cannot locate the necessary files to launch. To fix this issue, I use the following steps.

Navigate to c:\ and right click on Users. Select properties. Under the General tab, look at the bottom for the Hidden selection. If there is not a check mark in the box, place a check mark there. Hit apply, select yes to apply to all subdirectories. If you clicked ok, you may notice that it disappeared from the right pane once it finishes. It should still be listed under the tree on the left. Right click on it again. This time remove the check mark and apply to all subdirectories. Once it has finished, your files in the Users directory should reappear and Catalyst Control Center should function normally again. This has worked in all cases that I have encounterd so far. Hopefully this works for you as well..

Thanks a lot! I had the same problem as FREDFARRIS (desktop dissapeared and users map was not visible in the left part).

But it works when you don't close your (Users-map) properties-window and do the hide - unhide part. Thanks man!

Thanks for this solution.  I was able to follow the steps, however the "users" tab has actually disappeared from the tree on the left and now I don't know how to unhide everything . . . PLEASE HELP!!!

I'm not sure if you have your issue fixed by now or not. Unfortunately, the answers page does not sent a notice when there is a new question.  (These instructions and the previous ones are for Windows Vista, please make sure this is the operating system you are using.) Try this to see if users  folder will show up again. Click on the start button, then click on "computer".  Then click on "c:".  Now go to the menu bar and click on "Tools", then "folder options". then "view". Put a mark next to "show hidden files and folders", and take the check mark away from "hide protected operating system files". Click "OK" and check to see if the users folder has returned.
