File versions

Greetings,

I am evaluating InstallAware as a move up from our old Wise installer. One thing you could do with Wise was specify to install a file if the version number was the same or greater than the file on the system. I don't see this capability in InstallAware - the only thing I see is a checkbox to never overwrite - but it's not based on the file version. Am I missing something?

Thanks for your help!

Dear User,

The Windows Installer engine behavior is to overwrite files on the target system only if the ones you are copying are newer.
This behavior cannot be changed with the Windows Installer engine.

Similarly, the Native Engine by default will not overwrite files on the target system if the ones you are copying are not newer, however overwrites may be forced by setting the pre-defined variable NATIVE_OVERWRITE_OLDER to TRUE. However, this is not recommended as it may compromise target system integrity and may break other applications.

NOTE
InstallAware Native Engine is designed to provide a faster, non-transactional alternative to the Windows Installer engine. The native engine may be used stand-alone or as a complement to the existing Windows Installer engine.

Please refer to IA documentation for more information regarding Native Engine functionality.
