  1. I Put the 64-bit DLL File in System32 and it was Changed to 32-bit


    I put the 64-bit DLL file in the System32 folder, and the 64-bit DLL file in the System32 folder was changed to a 32-bit DLL file. I do not know what just happened to the DLL file that I put. What was it that happened? This issue should be fixed.

    The DLL has not changed. A DLL cannot be changed by editing a few bytes. That would take essentially a rewrite.

    The issue is with the exe64bitdetector which is itself a 32 bit program. This has implications in this situation.

    In a 64 bit OS the "system32" folder is used for 64 bit system files while the "syswow64" folder is used for 32 bit files. There are good reasons for this which I won't go into here. When a 32 bit program tries to access "system32" it will be silently redirected to "syswow64" which contains the files it needs. This allows older 32 bit programs that predate 64 bit systems to work as expected with a 64 bit OS. You must have a 32 bit "xvidvfw.dll" file in "syswow64" or you would get an error.

    exe64bitdetector.exe, being a 32 bit program, will actually see files in syswow64 instead. Use the program to check any DLL in system32 and you will see they all are reported as 32 bit. A 32 bit program can be designed to get around this redirection but even the latest version of exe64bitdetector.exe does not do this.

    Instead of specifying "system32" in the comand line you can substitute "sysnative" instead. This will alow you to actually access the system32 folder. This only works for 32 bit programs running on a 64 bit OS. Don't look for a "sysnative" folder as it does not exist.

    When a 32 bit program tries to access the "Program Files" folder it will be redirected to "Program Files (x86)" for similar reasons.

    As I said, things are not always as they seem.
