Setting default icon works for *c.exe (command line) and not for *.exe (window app) version

[alewir]

Setting default icons with RCEDIT for window version of *.exe files (from distribution) does not work:
RCEDIT.exe /I WinRun4J.exe EclipseFile.ico

Although it works fine for command line version of *c.exe files (from distribution), e.g.
RCEDIT.exe /I WinRun4Jc.exe EclipseFile.ico

Same for other (my own) .ico files.

NOTE: The problem was in my configuration - Windows cache caused displaying different icon than the actual one.
