Hello all, I have defined a system search to find whether an application(RTX) have been installed, the system search will check the following registry key HKLM\SOFTWARE\Tencent\RTXC, registry value: INSTDIR, and save the search result as an property "RTX". Here is the strange thing, when I install RTX on a 64 bit OS to its default Program Files (x86)folder, this system search can take effect. When I install RTX to Program Files folder, the system search seems doesn't work(I have defined an install condition "RTX"), my installer will tell me I haven't installed RTX...
I have tried the option "Search the 64-bit portion of the registry", still doesn't work...By the way, my installer only includes 32 bit components. What could be the reason of this behavior, please help.
