Hello, There is a script buglet in .../uni_con/includes/core_function_inc.vbs circa line 421. The code assumes that there is a CommandLine to give to the Split function. Sadly, there are times when there is a null (Nothing) in that field. It can be patched in the short term by changing that line: OLD: split_array = split(item.CommandLine," ") 'Split string at " " NEW: split_array = split(item.CommandLine&" "," ") 'Split string at " " NOTE: this is NOT a long term solution. Just a patch you can apply to get past this in 8.7.3. The problem is possibly caused by there being another program hogging port 80, but it is running as a service, and you don't have permission to get its CommandLine from the OS. Running Start_as_program.exe as the local system Administrator might help. -Jesse
