IDM is installed, but my browser shows error message that it cannot launch IDM. Why can it happen?

Browser shows error that it cannot launch IDM

If you see above message and IDM is installed, there are 2 possible reasons:

1. You use Windows ARM

If you use device with ARM processor and it has Windows ARM installed or you use Parallel Desktop to run Windows on Apple/Mac computer, Advanced browser integration will not work because IDM network driver does not support ARM architecture.

Latest builds of IDM also have problems with IDM browser extension on Windows ARM. You can install latest stable build 6.41.17:

Advanced integration still will not work, it never worked on ARM, but browser extension and catching downloads from browser should work in build 17 without Advanced integration.

2. Your system does not support SHA-256 digital signature Microsoft technology

You use Windows 7, Vista or Server 2008 system without installed updates to support SHA-256 digital signature Microsoft technology that it required for IDM network driver. Please read how to install updates to support SHA-256 technology.
