I'm building a upgrade and the AI installer package prior to this did not use the 'Permanent' or 'Never Overwrite'
component properties... so within the 'Registry' tab, I selected the right-most tree-view leaf
(Current user/Local machine // Software // Manufacturer // ProductName), then using the registry key editor,
selected 'Preserve key content' with a condition of OLDPRODUCTS on the Operations tab.
The goal is to not blow away the registry values currently in use that had been created by the older installer package.
When executing the new installer, I get the error: "Could not open key: \UNKNOWN\Software\_myMfgName_\_myProdName_'
Verify that you have sufficient access...."
In regedit, you can see that HKEY_LOCAL_MACHINE\SOFTWARE\_myMfgName_\_myProdName_ does in fact exist.
Any clue as to the issue? Is it significant that in the Registry tab the path includes 'Software', yet in regedit it's upper cased as 'SOFTWARE' ?
