[Wine] langpack.exe cannot be varified

[fmpfmpf]

i used wine to install a Windows program.
At the end of the installation, it says:-
"The publisher of the data "C:\windows\temp\VSD8b30.tmp\dotnetfx\langpack .exe cannot be verified."

i looked through the files and found out that "C:\windows\temp\VSD8b30.tmp\dotnetfx\langpack.exe " does not exist.
there isnt any langpack.exe, instead there is dotnetchk.exe.
i didnt get this problem when i installed it in windows.

What is wrong?
thank you very much
