New Post: System.IO.FileNotFoundException when selecting run times From/To dates on Vista and Win 7

At the moment I'm running into this problem on 64 bit Windows 10 Pro Insider Preview Build 10158. Same call works on 64 bit Windows 8.1 Pro.

System.IO.FileNotFoundException, The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
at Microsoft.Win32.TaskScheduler.V2Interop.ITaskFolder.RegisterTaskDefinition(String Path, ITaskDefinition pDefinition, Int32 flags, Object UserId, Object password, TaskLogonType LogonType, Object sddl)
at Microsoft.Win32.TaskScheduler.TaskFolder.RegisterTaskDefinition(String Path, TaskDefinition definition, TaskCreation createType, String UserId, String password, TaskLogonType LogonType, String sddl)

Used .NET-Framework 2.0 - Version 2.3.4.0
