Re: Get Registry Key Value fails on 64 bit?

Aha, okay If you need help, just let me know. We are doing this x86 / x64 stuff for 10+ years and UAC for more than 7 years now

Good luck with your project.

Oh, I wasn't referring to the SB functionality. The feature in SB is great - I'm sure it will help us work around the problem in the future.

My annoyance is mostly due to deadline-related pressures, and discovering a 100% silent Windows "feature" this late in our testing. Thanks for your help.

64-bit keys are are stored in the following registry sub key:

HKEY_LOCAL_MACHINE\Software

To access the 64-bit branch, you simply switch the installer into 64-bit mode and then you can access the native 64-bit resources. Don't forget to switch back to 32-bit mode after you have processed the 64-bit part.

So even though the request is made for the exact correct registry path, Windows silently redirects the call to the WOW6432node branch because the SetupBuilder installation is a 32 bit app? Neat (but annoying).

Re: Get Registry Key Value fails on 64 bit?

Here is an example from one of the include scripts. It reads the 64-bit registry keys when running on a 64-bit OS.

The same key as 32-bit looks like this on x64 systems:

HKEY_LOCAL_MACHINE\Software\WOW6432node\Microsoft\ Microsoft SQL Server\MUNISOFT\setup\SQLPath

Yes, except on the 64 bit machine the SQL server gets installed as a "legit" 64 bit app, so the registry is actually in the same place on a 64 bit machine (it does not) exist in the WOW6432node branch.

However, from your documentation I take it that the installer - as a 32 bit app - has its registry call automatically redirected to WOW6432node?

I am afraid I don't understand the question, sorry.
