Old 16-bit setup.exe in Windows XP can not run. In Task Manager you can see ntvdm.exe, wowexec.exe and setup.exe. But it nothing do, only stay in process list.
For me it happens for InstallShield installer of 1ะก:7.7. But it can be for any 16-bit installer.
In safe mode of Windows XP setup.exe must run normally.
                        
You need check next things:
1. Set in registry param
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOWtoyesif it set tono.2. Go to
TEMPfolder and delete all entries which possible.3. Open
Task Managerand kill all not necessary processes. Leave only system processes.3 item is most important. Some application can use some resources and prevent work
setup.exenormally.As far as I know problems can be if run some of
Nero Scoutprocesses (NMBgMonitor). But not only its. In my case it be something other.Others solutions from internet:
