Windows:
The Zoiper installer for Windows contains both a 32 bit build and a 64 bit build.
- The 32 bit version will work on both 32 bit and 64 bit windows
- The 64 bit version will only work on the 64 bit windows.
Which version to install ?
There is no real benefit in using the 32 or 64 bit version of Zoiper, but the choice matters for the integration with the Outlook installed on your PC. If you select the wrong version, the integration with Outlook will not work.
If you are using a 32 bit version of Outlook / Office, then install the 32 bit version of Zoiper.
If you are using a 64 bit version of Outlook / Office, install the 64 bit version of Zoiper.
