c++ - Strange behaviour with RegQueryValueEx whitch return value of another register -


i want path of excel.exe registry. used following:

i using windows64bits

 regopenkeyex(hkey_local_machine, szkey, 0, key_read, &hkey)

with 

szkey = "\classes\clsid\{excelclsid}\localserver",

this register contains "c:\progra~1\mif5ba~1\office15\excel.exe /automation"

used excel.exe path

regqueryvalueex(hkey, null, null, null, (byte*)szpath, &csize)

so when building solution platform x64, path

c:\\progra~1\\mif5ba~1\\office15\\excel.exe /automation

which fine, when building solution win32 platform following path

"c:\\program files\\microsoft office\\office15\\excel.exe" /automation

which strange because value stored in following registry

hkey_local_machine\software\wow6432node\classes\clsid\{excelclsid}\

am missing here?

the windows registry maintains, more or less transparently, different information 32-bit , 64-bit applications running in same environment. wow6432node see indicates value key specific 32-bit applications running on 64-bit version of windows.

you can disable default registry redirection (see regdisablereflectionkey), in majority of cases isn't want do.

see information on registry redirection here.
