I have used the ORCA MSI File Editor a few times to remove stupid restrictions from MSI files.
It is a pain to get as it is part of the Platform SDK - which is over 250MB whereas ORCA is about 1.6 MB
I found that you can download it from this URL http://astebner.sts.winisp.net/Tools/Orca.zip
Orca.exe is a database table editor for creating and editing Windows Installer packages and merge modules. The tool provides a graphical interface for validation, highlighting the particular entries where validation errors or warnings occur.
Note: If you are wanting to remove restrictions on a setup program from installing check the Launch Condition item as shown in the above image, as this is usally where all the checks are made.
This tool is only available in the Windows SDK Components for Windows Installer Developers or from the URL above
It is provided as an Orca.msi file. After installing the Windows SDK Components for Windows Installer Developers, double click Orca.msi to install the Orca.exe file.
orca [<options>][<source file>]
Orca.exe uses the following case-insensitive command line options. A slash delimiter may also be used in place of a dash.
Orca.exe uses the following case-insensitive command line options with merge modules. A slash delimiter may also be used in place of a dash. When performing a merge the -f, -m and <sourcefile> are all required.
