@egemen post:40

It seems we have a bug with 16 bit applicaitons. We will fix this issue this week. Until we fix it, a temporary fix would be renaming guard32.dll in c:\windows\system32\guard32.dll to something else and restarting your computer. When we update CIS, you can restore it back.

Sorry for the inconvenience.
