Windows 10: Automatic detection of the 32/64 bit character of my executables.

Some of my C++ code is depending on the 32/64-bit character of my executables. Solving this by #defining "x86" or "x64" will require adjusting the appropriate include file again and again. I tried "x64" without #defining it without any success. Perhaps WIN32/64? I would prefer an automatic detection perhaps by the program's Propertiies. I suppose in an emergency there might be a function call returning an appropriate value. I would consider this an emergency but I don't know any appropriate function Can any more experienced coder help me?

:)

 

Why will using any help function in my 64-bits executable kill this executable by an exception and simply execute its duty in an exactly the same 32-bits executable?

In or just before 2020 I detected this problem, described it and asked for help. Even some people recognized it. But no solution was offered and even the future was referenced. Now I have finished developing my project there will remain this ashtonishing difference between the 32 and 64-bits release versions: only the 32-bits executable will show any help from this same chm-file because the 64-bits executable will simply not show anything but even be killed all together by an exception. So far I didn't experience any other striking difference between both versions.

I developed over the years both versions using Visual Studio[Community]. All htlm-files were created/compiled by using the Microsoft HTML Help Workshop generating a flawlessly running chm-file with me supposing applicable to both 32 and 64-bits executables. I know the chm-files are 32-bits generated in the time the HTML Help Workshop was developed no 64-bits being available. The operating system Windows should be able to manage these differences. The exception took place not within my 64-bits executable but somwhere within Windows after the executable's call of HtmlHelp(). So I expected in both calls exactly the same but I remain surprised by the 64-bits executable's deviating behaviour. Can anybody help me? Looking around I am used to detect chm-files used to function as a help tool both for 32 and 64-bits executables. What will I be doing wrong many others are doing correctly?

I inserted my call of HtmlHelp() expecting this call applicable to both 32 and 64-bits versions. And everything written in C++. I didn't expect any diffference!

Windows 10 Pro 64-Bit to 32-Bit?

Hi,


Thank you for posting your query in Microsoft Community.



I understand your concern and will assist you to resolve this issue.

• 
  What is the name of the game?
  

If the system architect is 32 bit, then you can’t install 64 bit version of windows in it. I suggest you to run “winver” by pressing Windows + R, and check the version and bit.

There are some games that you can install it in 32 bit as well.

Windows 10 is the free upgrade for those users who has genuine key for Windows 7 and Windows 8.1 , normally it doesn't require activation, it's gets activated automatically, in case if you face an issue with activation the you can get back to
us.



For reference you can refer the link below and check if it helps (32 bit and 64 bit architect applies same to windows 10)
