FYI...
There was a change to APP SDK installer, the Clinfo.exe file is removed from C:\programfiles(86)\AMDAPP\bin\<x86/64> , as per new APP SDK new file structure/installer, the Clinfo.exe file will be copied to System folder with Catalyst-12.4 or later.
Catalyst-12.4 or later:
*Please check the Clinfo.exe files at C:\windows\System32\Clinfo.exe
No changes with Linux installer.
