RegKeys Not Deleted On Uninstall?

[H4nd0]

Hi Michael,

Write Registry Key HKLM\\Software\\Company\\Version\\Product, Something

creates the correct reg key + value. However, when I uninstall the key + value is removed (ie. Product) but the super-keys remain (ie. HKLM\\Company\\Version).

I thought IA takes care of this and removes all keys for me?

If not ... how do I force IA to purge the registry of all keys and values it wrote?

TIA,

James

It will remove the parent keys if no further keys remain and if you originally created the parent. Otherwise, you can use Delete Registry.

Hi Michael,

The installer did create all the keys/values.

The uninstaller _didn't_ remove the top level keys (but did remove all the sub values).

Is this normal behaviour or a bug?

Cheers,

James

Hi James,

It certainly seems abnormal to me - but Windows Installer takes care of all that internally, so it might be a good idea to run the install and uninstall with logging enabled first, before we jump to conclusions.

It would appear the installer is creating it's own registry keys and the creation of these keys is not even logged (!!!) ... it looks like the installer is grabbing something out of the project settings.

So here on install it's creating (I don't know where this is happening):

SOFTWARE\\FireDaemon Technologies Limited\\FireDaemon\\1.9

and then in the MSI code I create keys under here (which is where I want them):

SOFTWARE\\FireDaemon Technologies\\FireDaemon\\1.9

When the uninstall happens the former is being orphaned. Here's the logs (install then uninstall for all RegAdd and RegDelete events):
