Help installing PCAP WPCAP in Windows 7 64 bits (syswow64-system32)

I saw that there are several cases but I couldn't find a solution.

Which is the problem?

wpcap is not compatible with wireshark. I understand that NPCAP is needed to fix the compatibility issue. Can i use Wireshark whitout fix this? absolutely not.

What i see?

I noticed that when i run the NPCAP installer it will search for wpcap DLL in "c/System32/NPCAP/wpcap.dll" which is not there. it's actually in syswow64 folder (also packet DLL which looks related).

What i have done?

I deleted both dlls manually and tryed to install them again. (ver 4.3 i think) then continue whit NPCAP. (Same issue). Tryed to delete both manually and then run NPCAP (Same issue). After this wpcap sets to 5.0...

There is possible to specify from which path NPCAP should read those dlls? I read that it is not convenient to manually copy them into the folder because it could cause problems.

Also tryed that on "Safe Mode reboot".

Could you help me? this is a Windows 7 Ultimate 64 bits.
