[Win8.1-64bits] Wow6432Node/RegDBExist : can't read 64 bits key

[Lionel_13]

Hi,

I installed Java 1.7 - 64bits in Win7-64bits and Win8.1-64bits OS.
My registry looks like "HKLM\\SOFTWARE\\JavaSoft\\Java Runtime Environment\\"
The registry is OK because it's a 64bits application i've installed.

In my Installshield project, I want to read this key with the "RegDBExist" command.
The command fails because it doesn't find this key.

This command success only if the "HKLM\\SOFTWARE\\Wow6432Node\\JavaSoft\\Java Runtime Environment\\" key exists.

Could you tell me how I can read the right 64 bits key in my registry ?

I try to execute the "Disable(WOW64FSREDIRECTION)" command before installing Java, and before executing the "RegDBExist" command, but it doesn't work anymore.

Thanks
Lionel

If you have not, please refer to RegDBKeyExist.

Yes, I read the RegDBKeyExist doc and I saw the "Additional Information".

I executed the "Disable(WOW64FSREDIRECTION)" command before installing Java, and before executing the "RegDBKeyExist" command, but it doesn't work anymore.

Any other idea ?

You need the "REGDB_OPTION_WOW64_64KEY"-Option to read the 64-Bit part of the registry´.
