System.Diagnostics.Process and windows 10

Hi,

I use a dotnet variable to open a hyperlink in NAV 2009R2 RTC.
But after upgrading a pc to windows 10 the specic functionality returns an error.

I used the following locals

ReturnUrl	Text		250
Pos	Integer		
proc	DotNet	'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.Process	

I used the following code:

//Default DMS url containing a %1
ReturnUrl := "DMS Document Url";

//Replace %1 with searchterm in hyperlink
Pos := STRPOS(ReturnUrl,'%1');
ReturnUrl := DELSTR(ReturnUrl,Pos,STRLEN('%1'));
ReturnUrl := INSSTR(ReturnUrl,VarText,Pos);

proc := proc.Process;
proc.StartInfo.FileName := ReturnUrl;
proc.Start;

When calling this function after upgrading, I get the following error



"This message is for C/AL programmers. The call to member Start failed. "

Does anyone have a suggestion to solve this issue?
