64 Bit Registry Uninstall Information

[Matthew Wieder]

I wrote an MSI package that used the path found at
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft .NET
Framework 2.0\InstallLocation to determine where the .NET bin directory was
installed. However, on 64 bit systems, that path no longer exists. Where is
the new location which gives the uninstall information on a 64 bit system, so
I can find the installation path?

Did you check in (drive letter):\WINDOWS\Microsoft.NET?

There are both 32-bit and 64-bit folders with additional
folders for each version there.

P.S.

It appears to be in the same location in XP 32-bit, also:

C:\WINDOWS\Microsoft.NET\Framework

I need a registry key that points me to the install location on any machine;
I don't need the actual file system path.

Re: 64 Bit Registry Uninstall Information

My Windows XP Pro x64 64-bit (WINDOWS\regedit.exe) registry
entry is:
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft.NET
Framework 2.0 (x64)\InstallLocation

And in the 32-bit (WINDOWS\SysWOW64registry\regedit.exe)
registry it's:
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft.NET
Framework 3.0\InstallLocation

Nothing about Framework 3.0 in the 64-bit registry and
nothing about 2.0 in the 32-bit registry.

How about HKLM\Software\Microsoft\.NetFramework\InstallRoot ?
