com - System.Runtime.InteropServices.COMException | vb.net -

i know question has been answered many times have tried previous suggested resolution.

1.) target cpu x86

2.) have registered ocx , dll files

the application working fine on old machines (all os) not on new images.

here log :

framework version: v4.0.30319 description: process terminated due unhandled exception. exception info: system.runtime.interopservices.comexception @ system.windows.forms.unsafenativemethods.cocreateinstance(system.guid byref, system.object, int32, system.guid byref) @ system.windows.forms.axhost.createwithlicense(system.string, system.guid) @ system.windows.forms.axhost.createinstancecore(system.guid) @ system.windows.forms.axhost.createinstance() @ system.windows.forms.axhost.getocxcreate() @ system.windows.forms.axhost.transitionupto(int32) @ system.windows.forms.axhost.createhandle() @ system.windows.forms.control.createcontrol(boolean) @ system.windows.forms.control.createcontrol(boolean) @ system.windows.forms.axhost.endinit() @ restaurant.frmmain.initializecomponent() @ restaurant.frmmain..ctor()

here how registering files :

c:\windows\microsoft.net\framework\v2.0.50727\caspol -q -machine -addgroup 1 -url file://c:/xyz/* fulltrust -name "v drive"

regsvr32 c:\xyz\crystl32.ocx

regsvr32 c:\xyz\mscomct2.ocx

regsvr32 c:\xyz\msdatgrd.ocx

regsvr32 c:\xyz\cpeaut32.dll

regsvr32 c:\xyz\msstdfmt.dll

crystal reports runtime engine .net 4 framework in installed on system (both x86 , x64).

i had issue once.

i ran visual studio administrator. make sure know setting platform build: anycpu, x86, x64

for x86 try using anycpu!

try debugging issue read article microsoft said can debug exception occurring by:

debug > exceptions... , use find option locate system.runtime.interopservices.comexception. tick option break when it's thrown , debug application.
