.ocx installed in syswow64 instead of system32

[Marion List]

The .ocx file is always copied and registered in system32 as i express with 

{sys}  on all our computers. Now we got a new computer and with the same .iss he 

puts it in Syswow64 and trys to register it. which gets an exit code 03.

Hi,

Syswow64  is the correct directory for 32-bit files on 64-bit Windows.

Is your .ocx a 32-bit file? If not, see the 64Bit.iss example script.

Greetings,
Martijn

Hi Martijn, thanks for your quick answer. 

My .ocx file is a 32 bit file and i want it to be installed in System32 folder. How can i do this. And why is it done correctly on our other PC's ? 

Thank you,  greetings

32 bit file is supposed to go into syswow64. Because when 32 bit
program is run, it sees contents of syswow64 as system32. So that ocx
would not work then for 32 bit programs, of you but it into system32 on
64 bit windows.

Are other pc-s with 32 bit windows?

Hi, thanks for all answers, 

Problem is solved. Virgo you are right all files go to SYSWOW64. But in the end that was not the problem. A missing .ocx was the problem. 

It said it could not be registered.... but that .ocx needed another .dll to be registered, and that one was missing. 

Thank you all... my fault 

Have a nice day
