System Type (CPU ARCHITECTURE)
- x86 -refers to 32 Bit CPU
- x64 refers to a 64-Bit CPU
- x86-64, therefore, means that 64 Bit Processors support both 32 bit and 64 Bit platforms
- x86-32, therefore, means that 32 Bit Processors support only 32 Bit platforms
Operating Systems You can install
| RUNNING ON | 32-Bit CPU | 64-Bit CPU |
|---|
| Windows Platforms | x32-based processor | x64-based processor |
| 32 Bit Windows Platforms | 32-bit operating system | 32-bit operating system |
| 64 Bit Windows Platforms | ❌ | 64-bit operating system |
You can not install a 64 bit operating System on a 32-Bit-based processor
You may and can however install a 32-Bit operating system on a 64-Bit processor
Applications you can install and the Installation directory
| 32-Bit CPU | 64-Bit CPU | Installation directory |
|---|
| Application Type | 32-bit operating system | 64-bit operating system | Program Files |
| 32 Bit Version | ✔️ | ✔️ | C:\Program Files (x86) |
| 64 Bit Bit Version | ❌ | ✔️ | C:\Program Files |
