Peter,
That worked perfectly =)
I thought I'd tried this at some point whilst debugging but clearly I
was mistaken...
Thanks,
Liam

It can be immediate if you schedule it after InstallFinalize.

Subject: [WiX-users] Accessing Regsitry Values from an Immediate CustomAction
Hello,
I have a wix based installer that writes some registry values using the
standard wix registry element a bit like:
RegistryValue Action=write Type=string Root=HKMU
Key=Software\Company\Key Name=KeyName Value=1/
Is it possible for me to be able to read these values from a *immediate*
custom action? If so when do I need to schedule it?
I've currently got an immediate custom action that is scheduled *after
WriteRegistryValues* but it doesn't seem to be able to read the written
entries: RegOpenKeyEx returns ERROR_FILE_NOT_FOUND when trying to open the
relevant key with read access. Custom action xml is:
CustomAction Id=MyCustomAction Impersonate=yes Return=ignore
Execute=immediate BinaryKey=MyCustomActionDll
DllEntry=MyCustomAction /
and the sequencing is:
InstallExecuteSequence
Custom Action=MyCustomAction After=WriteRegistryValuesNOT
Installed/Custom /InstallExecuteSequence
*Other Notes*
* In the example ALLUSERS is 1 so the registry values will end up in
the HKEY_LOCAL_MACHINE key.
* As a result of the above the installation is given elevated privileges.
* I've got the custom action's impersonate value set to yes as there
are various pieces of user information I want to access from the CA.
AFAIK this shouldn't be an issue as long as I only want to *read*
keys from HKEY_LOCAL_MACHINE, which is the case. Any modification
happens in the HKEY_CURRENT_USER key.
*Environment*
* Compiled using Wix v3.5
* Installing on a Windows 7 Enterprise (SP1) machine
