error code 0x80040154

I get the impression you don't speak English well, however you need to explain your problem more clearly. Perhaps get someone to TRANSLATE for you.

All I get when searching is this but without knowing any other specifics about your situation it's hard to help:

1) Windows version? (i.e. Windows XP 32-bit, or Windows 7 64-bit)
2) WHEN does this problem happen (launching a specific program?)
