Thanks for your response.I know how to solve this problem.but I didn't know
why I can install correctly sometimes?Is thant any error in my installing?

Try these things:

1) That your installations are from the same source
2) You are using same installation options (for OS, SQL, Project & WSS)
3) Your sequence of installation is same including service packs for these
products

I think variation in above factors can cause your installation to act some
what differently than similar installations. It might be due to DLL / System
settings etc mismatch.

Dear NorthSky,
I'm facing the same error, one of my instlallations works fine when it comes
to synchronize the project professional with the server, while the other is
always givinf Project Server Spooler Error (0x80004005) System Error!!, and
in the server's event log I found:
Error Number: 0x80004005
Description: <Description><![CDATA[Assert Detected. The error code was also
included.]]></Description>

Is this what you were facing? how did you solve it? (I installed hotfixes
for both server and professional)

Thanks a lot
