Fault Tolerant Heap (FTH)


Recommended Posts

I had some repeated glitches when opening a 3D view and subsequently, every time I start CA, I get "Windows Fault Tolerant (FTH) has been enabled for this application.  This may degrade performance".  It REALLy degrades performance and once hit, you're stuck with this.


Although there are several Web recipes to get rid of this, he only one that worked for me is this:

  • Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\FTH" in your registry
  • Look for value 'Enabled' and set to 0
  • Look for subkey 'State' and delete the value that represents the CA executable.


You can also view Microsoft's article on this here.


Interested in seeing if others have come across this 'Microsoft feature'.
