Why can't a 64-bit program run on a 32-bit copy of Windows? How does my PC know that I'm running a 64-bit program? Does the program have a piece of code telling Windows that it's a 64-bit program or does Windows simply fail to execute it?
For another, the actual machine-code instructions inside the program are different. (That's kind of the whole point of having different architectures, by the way.) The 64-bit x86_64 architecture has more instructions than 32-bit x86 had, and 32-bit x86 had more instructions than 16-bit. (And things like Alpha or ARM or Itanium are so different that there's very little that could even be compared.)
Why can't a 64-bit program run on a 32-bit copy of Windows?
A 32-bit program stores the various locations where it has stored its data in 32-bits. And since it is possible to store 32-bits in 64-bits of storage, Windows will happily run the program while filling the other 32-bits of the 64-bit appropriately.
A 64-bit program on the otherhand uses 64-bits to indicate the locations. Since it is not possible to store 64-bits in a 32-bit storage without throwing away half of it, Windows will refuse to run a 64-bit program on a 32-bit computer.
Does the program have a piece of code telling Windows that it's a 64-bit program or does Windows simply fail to execute it?
Every program has a header, that tells Windows, every thing it needs to know about how to run the program including if it is a 32-bit application or a 64-bit application.
I saw a significant difference in file size of the two versions of the same program, so I think it's the code that's different. Is it possible to modify the code and make the program run?
64-bits occupy twice the amount of memory as 32-bits. That is why 64-bit programs are larger than their 32-bit counterparts.
These memory locations only make up a fraction of a program; the majority of it being instructions (which remain the same size) and stuff like text and icons. Since only the memory locations double in size, the 64-bit version of a program is only slightly larger than being double the size.
Because 2^64 is a much larger number, it's obvious that 64bits programs can access a much wider range of values; they can see/use a lot more memory. Large enough that you likely don't know the SI prefix: 16 exbibytes. What's an exbibytes? Large enough that nobody will really care for the foreseeable future.
These quick command line instructions will get you set up quickly with the latest Miniconda installer. For graphical installer (.exe and .pkg) and hash checking instructions, see Installing Miniconda.
These three commands quickly and quietly install the latest 64-bit version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for Windows, change the name of the .exe installer in the curl command.
These four commands quickly and quietly install the latest M1 macOS version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for macOS, change the name of the .sh installer in the curl command.
These four commands quickly and quietly install the latest 64-bit version of the installer and then clean up after themselves. To install a different version or architecture of Miniconda for Linux, change the name of the .sh installer in the wget command.

I find this bizarre in the extreme. First there was the (still on-going) disastrous rollout of the MacOS version "supporting" Apple Silicon (IIRC, they *still* aren't fully supporting it) and now I find out (when I need to switch platforms) that they still don't have a 64-bit version for Windows! How long has Windows supported 64-bit software? Over 20 years ago, maybe? Completely inexplicable. Definitely switching to iDrive or one of the other excellent alternatives offering 21st century support when my subscription expires.
Note: configure now enables DCO build by default on FreeBSD and Linux. On Linux this brings in a new default dependency for libnl-genl (for Linux distributions that are too old to have a suitable version of the library, use "configure --disable-dco")
Note that OpenVPN 2.5.x is in "Old Stable Support" status (see SupportedVersions). This usually means that we do not provide updated Windows Installers anymore, even for security fixes. Since this release fixes several issues specific to the Windows platform we decided to provide installers anyway. This does not change the support status of 2.5.x branch. We might not provide security updates for issues found in the future. We recommend that everyone switch to the 2.6.x versions of installers as soon as possible.
The OpenVPN community project team is proud to release OpenVPN 2.5.6. This is mostly a bugfix release including one security fix ("Disallow multiple deferred authentication plug-ins.", CVE: 2022-0547). The I605 installers include OpenVPN GUI with a bug fix, as well as updated OpenSSL (1.1.1o).
The OpenVPN community project team is proud to release OpenVPN 2.5.5. The most notable changes are Windows-related: use of CFG Spectre-mitigations in MSVC builds, bringing back of OpenSSL config loading and several build fixes. More details are available in Changes.rst.
The OpenVPN community project team is proud to release OpenVPN 2.5.4. This release include a number of fixes and small improvements. One of the fixes is to password prompting on windows console when stderr redirection is in use - this breaks 2.5.x on Win11/ARM, and might also break on Win11/amd64. Windows executable and libraries are now built natively on Windows using MSVC, not cross-compiled on Linux as with earlier 2.5 releases. Windows installers include updated OpenSSL and new OpenVPN GUI. The latter includes several improvements, the most important of which is the ability to import profiles from URLs where available. Installer version I602 fixes loading of pkcs11 files on Windows. Installer version I603 fixes a bug in the version number as seen by Windows (was 2.5..4, not 2.5.4). Installer I604 fixes some small Windows issues.
The OpenVPN community project team is proud to release OpenVPN 2.5.3. Besides a number of small improvements and bug fixes, this release fixes a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606). Updated OpenVPN GUI is also included in Windows installers.
The OpenVPN community project team is proud to release OpenVPN 2.5.2. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking a server using delayed authentication (plugin or management) into returning a PUSH_REPLY before the AUTH_FAILED message, which can possibly be used to gather information about a VPN setup. In combination with "--auth-gen-token" or a user-specific token auth solution it can be possible to get access to a VPN with an otherwise-invalid account. OpenVPN 2.5.2 also includes other bug fixes and improvements. Updated OpenSSL and OpenVPN GUI are included in Windows installers.
Our MSI installer do not currently support the Windows ARM64 platform. You need to use our NSI-based snapshot installers from here. We recommend using the latest installer that matches one of these patterns:
The OpenVPN community project team is proud to release OpenVPN 2.4.12, the final release in the 2.4.x series. This is mostly a bugfix release including one security fix ("Disallow multiple deferred authentication plug-ins.", CVE: 2022-0547).
The OpenVPN community project team is proud to release OpenVPN 2.4.11. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking a server using delayed authentication (plugin or management) into returning a PUSH_REPLY before the AUTH_FAILED message, which can possibly be used to gather information about a VPN setup. This release also includes other bug fixes and improvements. The I602 Windows installers fix a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606). Updated OpenSSL and OpenVPN GUI are included in Windows installers.
Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them.
If you find a bug in this release, please file a bug report to our Trac bug tracker. In uncertain cases please contact our developers first, either using the openvpn-devel mailinglist or the developer IRC channel (#openvpn-devel at irc.libera.chat). For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at irc.libera.chat).
