It is possible for individual component installs to fail or do nothing if a newer version of the product is already installed
The best way to figure out the problem and solve it is to install any failed components manually as follows:

Start the KIOL installer exe and allow it to unpack to a temporary directory.
Write down the name of the temp directory and then cancel out of the installer.

Go to the temp directory where it unpacks and then go into the Setup subdirectory.
Look for a subdirectory with KIOL and run the kiol-850c10.msi file and see what happens.
Repeat this for any other components which failed to install one by one.

If you can open the Keithley Communicator and the Keithley Configuration Panel, then you should be good to go.
If not, what is the primary reason you are installing the Keithley I/O Layer?

Model 236 is not supported by KickStart.

"It seems RS232 connection will result in communication error when trying to read the data according to  Kickstart, but setting seems working"
--> RS-232 has never been supported. GPIB is the proper communication pathway to use with KickStart for this instrument.

The Data Logger app requires the instrument to have at least one scanner card installed.
The Data Logger will then make use of all scannable channels.

The DMM app does not require a scanner card. It uses the front or rear terminals to measure.

DMM & Data Logger licenses are as follows:
KICKSTARTFL-DMM-AN :  KickStart Precision Digital Multimeter Application Software; 1 year Subscription Floating License Option
KICKSTARTFL-DL-AN      : KickStart Data Logger Application Software; 1 year Subscription Floating License Option
