Windows 7 Installer Error in fresh Windows 7 Ultimate installation !!!

[Anti]

hi there,

i installed Windows 7 Ultimate x64, build 7600 now 4 times on my Laptop (Samsung C2D 1,6GHz 1GB RAM)
1install: after updating the win7 and installing Office 2007 OLP the windows installer is something corrupt i dont kow.
-> i cant install any kind of msi nor peace of software which use the installer eg. adobe reader oder sun java
2install: i just wantet to test if the problem exist if i dont install office , so i just did the windows update and tried to install adobe reader. same problem
3install: i just installed a fresh windows 7 ultimate and tried to install adobe reader. same problem.

Problem Translated from german to eng.: dont care about syntax ^^
Windows Installer:
This Installation Paket could not be opened. Make sure the pakage exist and u have access to it.
Or let the vendor proove if this is a valid windows Installerpakage.

Do`s to fix the problem (solutions)
- make the registry tweak for the SQM, disabling quality bla... (known beta error) doesnt fix the problem
- tried to set a new temp dir with new ntfs rights (doesnt work)
- give ALL users access to the temp dir (doesnt work)

Consider that i testet same OS on my Desktop Machine, no errors at all there...
I didnt had have the problem as i was testing the RC1 Ultimate on the same Laptop.
Its gonna make me crazy... ;(

im out of ideas now, can somebody help me ?

Have you right clicked the installers and ran as admin? often overlooked life saver.

i already tried to install the x32 of ultimate. same problem. direct after install im not able to install any windows installer based aplication....

is it possible that the error is based on the translation ?
the RC 1 was english and worked fine
