Internet Explorer getting crashed after upgrading App-V 5.0 SP2 or SP3 to App-V 5.1

After upgrading from App-V 5.0 Sp2 or App-V SP3 to App-V 5.1 , Internet explorer starts crashing for no reason.

The Application event log shows two possible errors:

1.Faulting module : EMET.DLL
2.Faulting module : NTDLL.DLL

This is a known bug with App-V 5.1. Some possible workaround is to either revert back to 5.0 or follow the below steps.


Remove the following lines in the registry and IE 10 / IE 11 will stop crashing.

HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / AppV / Client /Virtualization



%ProgramFiles%\Internet Explorer\iexplorer.exe

%ProgramFiles(x86)%\Internet Explorer\iexplorer.exe

You can also try removing the App-V 5.0 earlier versions manually and then install App-V 5.1 instead of upgrading to avoid this issue.

Though the above said step is just a workaround, it is not a recommended way to bypass this issue. We need to wait for Microsoft to come up with possible fix or service pack soon.
