Hi,

I have a config files which needs to be installed in different locations for Win7 32-bit and 64-bit. In InstallScript, how to check if the target system is a 32-bit or 64-bit?

Thanks!

You can change the Directory of the Component using a Set Directory Custom action with condition VersionNT64.

Thank you!

I also need to update a config file at install. But I am unable to use INSTALLDIR. How to use this VersionNT64 property in my InstallScript?

Thanks!
