In my windows 7 amd64, I have an .exe which depends on libeay32.dll. Both, library and exe, are compiled for 32 bits. I have copied the exe to C:\Program files (x86)\app\bin and the dll to C:\Program files (x86)\app\lib. To ensure the correct working, i have added C:\Program files (x86)\app\lib to the path, following this: http://msdn.microsoft.com/en-us/library/ms682586%28v=vs.85%29.aspx The program its correctly launched/executed when done from start menu->program, but not directly on the .exe !!!??? Using sysinternal process explorer, i can see the app is launched correctly. Using cmd, the app works perfectly. On Windows 7 64 bits, when i run the exe, i got a libeay32.dll not found error. Using dependency walker for 32bits on the exe, the library is properly located at C:\Program files (x86)\app\lib. Using procmon i can see its trying to open (note the lack of " "): "C:\Program Files(x86)\app\lib\LIBEAY32.dll". In Computer properties, i re-re-re-checked PATH, and its correct: "C:\Program Files (x86)\app\lib" I tried setting "%programfiles(x86)\..." or "C:\Program Files (x86)\..." buth fails also. Is there a know scenario/bug where setting "C:\Program Files (x86)" on path, lead windows try to load "C:\Program Files(x86)" instead???? Windows 7 amd64 bug? Altough its not necesary, i tried both regsrv32 on syswow64 and system32 without success. Do you know if theres a registry key, other than HKLM\System\CurrentControlSet\Control\Session Manager\KnownDLLs for 32 and 64 enviroments, like Wow6432Node ? Any ideas will be much appreciated.
