Missing datachannel.dll

[Jlh_4336]

when I try to install an app I get the error message

The code execution can not proceed because datachannel.dll was not found

What do I need to do?

This could be an error that is specific to the application you are working with. One thing that can be a key to troubleshooting the issue is identifying where the messages are coming from. If you feel comfortable doing so, providing the name of the application you are trying to install could help the community to better understand the problem. Other factors you might consider including are if you are performing an upgrade from a previous version, if you recently uninstalled a similar program, and/or if you may have recently un/installed a different program prior to attempting the installation of the app in question. Sometimes error messages like this can occur if the file is being used. If you have an older version installed or attempted to uninstall an older version prior to the installation, you might try logging out and logging back in or doing a full restart (simpler). Sometimes applications can leave artifacts from their previous installs. It's always good to double check when doing an application upgrade that requires a previous version to be removed.

I purchased BitTorrent pro, I uninstalled BitTorrent classic and now I get the error Datachannel.DLL could not be found and cannot install. I'm not sure whether I should have uninstalled the free classic version or not but cannot reinstall it either

Unfortunately, BitTorrent is known to be used heavily to download illegal media, and as such has become a common gateway for viruses. That said, the file might still be in use by a background service which BitTorrent uses to monitor the file system. Worst case scenario you might be dealing with a virus or root kit. I would advise you run a virus scanner, or if you don't already have one installed, consider having your system serviced by a professional and let them know you suspect a virus.
