Unable to slipstream update 10.1.1/.2/.3 in Acrobat Std 10.1.0

Hi everybody.

I'm struggling with slipstreaming updates into Acrobat X Standard v10.1.0.

I used the v10.0.0 and made an administrative installation in a new folder with

msiexec /a AcroStan.msi

After that I integrated successfully the 10.1.0 with

msiexec /a AcroStan.msi /p AcrobatUpd1011.msp

Installation runs successfully with the 10.1.0 package.

But when I try to install or integrate the 10.1.1 update I get the following error message:

I would be very happy if somebody could help me.

Regards

Johannes
