<pre>I have downloaded the official LLVM 3.7.1 32 and 64 bit windows installers.
Environment: Windows 10 64 bit.
First I have installed the 32 bit LLVM 3.7.1. The following registry key
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LLVM\LLVM had the default value set to:
"C:\Program Files (x86)\LLVM"
Then I have installed the 64 bit LLVM 3.7.1. The first thing that popped up was
this dialog:
---------------------------
LLVM Setup
---------------------------
LLVM is already installed.
Do you want to uninstall the old version before installing the new one?
---------------------------
Yes No Cancel
---------------------------
I have clicked on "No".
The registry key HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LLVM\LLVM defaul t
value was changed to "C:\Program Files\LLVM".
Please make sure that the 64 bit installer checks and writes to the 64 bit
registry "HKEY_LOCAL_MACHINE\SOFTWARE\LLVM\LLVM".
These paths are needed by tools to query the existence of LLVM on Windows.
