With the realeased of whatsapp version for PC and MAC i know many users have already download it and enjoying its work. I just noticed that some windows users are finding it difficult to install the App and when they try to do so, a message of this pop up: Installation has failed. There was an error while installing the application. Check the setup log for more information and contact the author.

As you already know its of recent that whatsapp launched the desktop version of the app and this new version of desktop app does not support voice call and nevertheless it is just a wrapper for the web version as everything is similar with the web version even though it is limited to only windows 8 and 10 but however you can be able to install it on windows 7.


WhatsApp Installer has failed. There was an error while installing the application

If you face this kind of error when installing whatsapp on your PC, then that means your windows system is not compatible to run whatsapp desktop App because your PC is not a 64 bit operating system but 32bit. The latest Whatsapp version for PC is only released to 64 bit operating system and if your system is a 32 bit operating system you can consider changing it to 64 bit operating system to enjoy the whatsapp for desktop.

However Another similar problem is hardware issue, if your PC is old and does not support 64 bit architecture, then you can't enjoy whatsapp for the time being because there was no official information on the released of whatsapp for desktop 32 bit operating system but we hope in the mean time a version for 32 bit operating system will be released.
