Hi,
I downlaoded SQL Server Express 2014 and double click to install it. The file decompress box appears. When it finished, it closed and then no other dialog / instructions appears.
I checked the SQL log file at TEMP folder and found that it attempted to remove .Net security code group node and then close the setup with code 0x00000000
Seems I cannot upload the whole log file here thus I copied some below:
