update.exe - Application Error

Hello @ all,

I have following problem with update.exe on a Fujitsu Tablet PC (OS: Windows
XP):

The Problem occurs the first time as I tried to install IE7 because there
was a problem to play embedded streaming media player videos with IE6.

Unfortunately, the installation aborted with an update.exe error.

An IE Error Log wasn`t written at this time . A Windows Media Player 11
Installation aborted with the same Error.

The Event Log (Application) shows following entry:
Source: Application Error
Categorie: None
Typ: Error
Event ID: 1000
Description:
Missed application update.exe, version 6.2.29.0, missed module ntdll.dll,
Verion 5.1.2600.2180, error address 0x00010de3


The System Event Log shows no Event which can be assigned to the Error
above.

An Examination of the Systemfiles with the command "sfc /SCANNOW" did not
announce any problem ;-(

Maybe it helps to replace the ntdll.dll, but how? Last but not least is the
HDD with an Encyption Tool (Utimaco SafeGuardEasy) coded (makes it not
easier...).

Please help!

Thanks!
