Hi Marcus & Tomer,
It appears this is an issue when running the installer on Vista or Win Server 2008 64 bit, where the 32bit registry hive did not have complete info about the installation component. This issue has been resolved internally in the latest installer bits, but as a workaround you can run an eleveated command prompt and type the following command:
msiexec /i <installerPath> IIS6COMPAITABILITYMODE=#1 /l*v c:\teapulselog.txt
Hopefully this will resolve the issue for you both.
