Configure the following Windows Registry PDA settings for each SCEC:
SHCE COM Disable. This registry setting is not present by default. Add this setting and set it to Y to disable COM Extensibility.
SCEC Dir.This registry setting specifies the location of the directory of the SCEC. All *.dll files in this directory are preloaded. This registry setting is not present by default; you must add this setting.
\program files\siebel handheld\scec
CAUTION: Specify a directory containing only SCEC .dll files. Using \Windows causes the application to attempt to preload all .dll files.
