There are two questions: first - how can I find out which version the application is? I mean 64 or 32-bit version. There is the simple command "file" in UNIX/Linux, does Windows have something similar? Thanks.
Second - I've bought the computer with Win10 which already was activated at the store. Now I can't change the account at Microsoft. Is it possible at all?
If the exe is in program files (x86) directory, it is almost certainly 32bit. If in program files directory, almost certainly 64 bit. However that is not 100℅ guaranteed.
There are many programs installed in PF64 or just PF without any additional parameters. They may may be compiled for 64 or 32 or even 16-bit platform.
A 64-bit version of Windows has both C:\Program Files and C:\Program Files (x86) Folders while the 32-bit version has only the C:\Program Files Folder. The (x86) Folder in 64-bit Windows contains 32-bit programs. Obviously change the reference to C:\ to whatever drive you have Windows installed on.
The matter is: you can install any new program to any directory you want. So, PF(x86) or PF do not mean anything. Many of my programs are installed in my home directory. I just want to know which program file was compiled for 64-bit Win10 version and which for 32-bit. Is it possible in Windows? It's so simple in any kind of UNIX/Linux, just type "file" command and that's all. Any analogs for Win10? Thanks.
Some of it may be true but since there was no mention of customization of program storage one has to assume the default settings are in place which is all I referred to.
True. Most people don't even realize that 70-80% of the programs that the installers can be unzipped with 7-zip to any folder and use as a portable. Ex: VLC player, 7-zip, WinRar etc...The matter is: you can install any new program to any directory you want.
Open task manager->Details and right click on the header then select "Platform"
Right click the file in Windows Explorer and select the compatibility tab. If compatibility settings are available for Windows 95 and later it is 32 bit. If it only goes back to Vista it is 64 bit. It can also be done by examining the file with notepad but that is slow for large files. I don't know of any other reliable methods that don't require third party tools.
