Hi,

I want to remove old registry entries which were added by older releases.
Let me explain my issue with example.
There was one build say 1 in which there was a registry entry "[HKEY_LOCAL_MACHINE\SOFTWARE\ABC\{99C41FDE-98E8-4608-8ECC-BE1940916AA7}]" in component say "Component1"..

A patch was created say 2 and under that patch the value of registry in"Component1". was changed to "[HKEY_LOCAL_MACHINE\SOFTWARE\XYZ\{99C41FDE-98E8-4608-8ECC-BE1940916AA7}]"

Now we have created a major upgrade say 3 and have removed "Component1" and hence the whole registry entry.

There is no registry entries if we install 3 .
However if we upgrade 1->2->3 and then uninstall the whole build the registry entries which were created while installing 1 still remains.

Do I have to write a script to remove this registry entry.(I tried using RemoveRegistry table but nothing worked).

Thanks,
Alex

Your change from version 1 to version 2 orphaned the ABC entry. I think it would have been best to use RemoveRegistry in version 2.
BTW: the registry entry isn't the key path of the component I hope.

But RemoveRegistry should work even in version 3 if it is populated properly. Plase post your settings.

Hi Stefan,

Sorry for the late reply.
Following are the settings that I used in RemoveRegistry after deleting NewComponent1 from Version 3(which is a major upgrade)

RemoveRegistry: HKEY_LOCAL_MACHINE

Root: 2

Key: SOFTWARE\ABC\{<CLSID value>}

Name: "-"

Component: NewComponent1

Note:
NewComponent1 was the component which was having the registry file in version 1 and version 2 and which was removed in version 3.

So in minor upgrade even if we modify the component value(without deleting them), it will make the original value orphaned?
what should have i done in version 2: Created a new component to have the new registry entry and removed the registry entry in NewComponent1 or should I have used RemoveRegistry

I thought under Component i should put the name of the component which was having the registry entry(which was eventually removed in version 3).

Thanks for clearing my doubt.
