Failed to Find Steam Error Fix

Thank you for contacting Steam Support.

Please try the following:

Click the Start Button, then "Run" (or hold the Windows key and press R).

Type the following and press OK:

regedit

Browse to the following path:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Locate and delete any entry for Steam.exe (Most likely C:\Program Files\Steam\Steam.exe)

Then, browse to the following location and remove any Steam.exe entry there:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Then, restart your computer and test the issue.
I actually had to delete the steam registry from AppCombatFlags/Compatibility Assistant then it worked but still check the layers folder for steam registry entrys|

Deleting the key made Ghost Master work for all of one day. Today I get home and, lo and behold, the white screen of death....one problem replaced by another

I have the same problem but when I looked in regedit there was no Steam entries in any of the locations you mentioned.
