I found the solution here.

Installer 2.0 doesn’t corrupt explorer.exe. The MSISIP.DLL
v2.0.2600.2 has a bug in it. You must download MSISIP.DLL v2.0.2600.0
such as from here
[url=http://support.microsoft.com/default.aspx?scid=kb;en-us;836013]
Do NOT double-click to install the install.exe file you download.
Instead, right-click to open install.exe with a ZIP utility such as
WINZIP.EXE and extract InstMsiW.exe from it. Right-click and open
InstMsiW.exe again with WINZIP. Now you can extract MSISIP.DLL
v2.0.2600.0. You should be able to simply drop it into the
C:\Windows\System folder, replacing the defective file. If your
system is not fixed, reboot. You may want to keep the defective file
instead of replacing it. I suggest you keep/ZIP both versions. If
you cannot replace the MSISIP.DLL file in Explorer, you will need to
replace it in MS-DOS mode.

When I install InstMsiA.exe (version 2.0.2600.2) the windows

displays
the
properties sheet and then deletes the tempory file. You can only
spot
it
doing this if the file is a few hundred MB, so I can’t be sure
it’s doing
this for small files, though if the file is really large (arround a
GB) it
doesn’t do it at all. I’ve been able to isolate the
problem to msisip.dll.
Explorer.exe is version 4.72.3110.1. I run with most options turned
off and
the following reg settings:..........................SNIP


Any ideas?
