IXP would not launch from Browser without giving error.
However, when from the IXP server, it runs fine.
IXP version: 18.104.22.16898
OS: Windows 2008 R2 SP1
This usually happens in case of corrupt Java executables (java.exe, javaws.exe) in %SYSTEMROOT%\SysWOW64
To resolve this issue, we can delete these Java .exes from %SYSTEMROOT%\SysWOW64, which let the browser find javaws.exe from the actual (valid) path C:\Program Files\Java\jre1.8.0_171\bin.
If this doesn't resolve the issue, raise a case with CA Support.
