Skyrim crashes to desktop after installing mods

After Skyrim’s release last year a lot of mods came out, for improving graphics and UI in the game.
However when I tried to install some – the game started to crash.

The reason for it, as it appears, was outdated game (i han the initial release version).
After installing the 1.5 update ( The Elder Scrolls V: Skyrim Update 7) the game stopped crashing.

The latest update can be found by file name: rupdate7-tesvs.rar
