The installation seems to be going fine when i reach the part; Setting AuthPersistence property for GroupExpansion EXT virutal directory. The installation fails with Error 0x80004005 (Unspecified error) occurred while executing command 'D:\ WINDOWS\system32\CScript.exe'.
After that the installation rolls back and i get the failure screen below.
Failure
[0xC3EC796A] MSI installation was unsuccessful. Please check the log file for more information.
I have no clue how to proceed as i am unsure what to do.
