From bddc0bee29a3f70057857bc20226d0929d46dbf7 Mon Sep 17 00:00:00 2001 From: Axel Gembe Date: Wed, 26 May 2010 09:38:46 +0200 Subject: [PATCH] fix wow64 registry mode on windows 2000 CMake fails to find any registry paths on Windows 2000 and according to regmon it fails with an access denied error. I double checked all the access rights and they are fine. After checking the access modes on MSDN I found that it says KEY_WOW64_32KEY / KEY_WOW64_64KEY are not supported on Windows 2000. CMake does not check if the current system supports Wow64 before applying these flags. This patch adds a check for IsWow64Process in kernel32.dll before adding these flags. Maybe this should be in a helper function, but I don't really know the codebase well enough.
