ICE35
ICE35 validates that components containing compressed files stored in a cabinet file are not set to run from source. With Windows Installer 2.0 or later, this restriction has been removed.
ICE35 queries the Cabinet column of the Media table to determine which files are compressed and stored in a cabinet file. It queries the File table to determine which components contain these files. Finally, it checks the Component table to determine whether the run-from-source bits are set in the Attributes column.
Result
ICE35 posts an error message if there is a compressed file stored in a cabinet file belonging to a component with the msidbComponentAttributesSourceOnly bit set in the Attributes column of the Component table. With Windows Installer 2.0 or later, this is changed from an error to a warning message. A package that supports only Windows Installer 2.0 and later has the PID_PAGECOUNT property of the Summary Information Stream set to a value of at least 200.
ICE35 posts warning message if there is a compressed file stored in a cabinet file belonging to a component with the msidbComponentAttributesOptional bit set in the Attributes column of the Component table. This warning message has been removed with Windows Installer 2.0 and later.
If multiple files in a component are in a cabinet file, ICE35 reports errors for each file that has the run from source bit set.
Example
ICE35 reports the following errors and warnings for the example shown using a version earlier than Windows Installer version 2.0.
| ICE35 Error | Description |
|---|---|
| ERROR: Component Component3 cannot be Run From Source only, because its member file 'File3' is compressed. | There is a compressed file stored in a cabinet file and this file belongs to a component with the SourceOnly bit set in the Attributes column of the Component table. To fix this error change the lower 2 bits of Component2's Attributes value to "00", meaning Local only, or remove File4 from the CAB file. |
| ERROR: Component Component3 cannot be Run From Source only, because its member file 'File3' is compressed. | There is a compressed file stored in a cabinet file and this file belongs to a component with the SourceOnly bit set in the Attributes column of the Component table. Because the files in a component do not all have to originate from the same media, ICE35 reports errors for each file in the component that is in a cabinet. To fix this error change the lower 2 bits of Component2's Attributes value to "00", meaning Local only, or remove File4 from the CAB file. |
