Hi, > On the other hand - it seems you have already tried to extract with 'setup.exe /a' - Indeed I have. > have you defined %SOFTWARE_ISERV%? I don't recall this as an environmental variable. Of course %SOFTWARE_ISERV% is defined. Its one of my own environment variables. And the error I'm getting is not 1619 (ERROR_INSTALL_PACKAGE_OPEN_FAILED) but 1603 (ERROR_INSTALL_FAILURE). The setup starts just fine, decompresses the install files and ... dies with 1603. - jens |
