Release Notes for OPC Core Components 106.0|Classic OPC: DA, A&E, HDA, XML-DA, etc.|Forum|OPC Foundation

Hi Mark,

The release notes for version 107 (“OPC COM Core Components Readme 107.24.pdf”) reads (highlight is mine):

The Core Components Merge Modules now use the MSI Component IDs that match the 105 release. This should prevent necessary components from being uninstalled when an application that uses the Merge Modules is uninstalled. This problem will still exist if a product uses the 106 release, however, there should be a smaller number of those products. Version 106 has been removed from the website because of the inconsistent Component IDs.

That said, there should be no reason to use the 106 release – simply grab the 107. If you specifically need the 106 version, please share the reason and, if it’s plausible enough, I’m pretty sure that the site administrator will at least consider making it available again (possibly with a warning similar to the above).

Cheers,
Helder Magalhães
