CLR20r3 error in WinForms application

we're having issue 1 particular application on 1 particular server. we've got dozens of installations of application have worked years, it's 1 customer's server can't execute it. application developed in vs2005 (we can't move 2010, 1 , assembly reference doesn't work in vs2008 or 2010 solutions , we've verified assembly's vendor case). server issues brand new server 2008 r2 current on system updates.

 

that being said:

1) can't capture unhandled exception @ either application or appdomain level...it crashes before involved , can't attach debuggers because process never starts

2) message we're getting is:

now, points out issue invalidoperationexception in routedesigner assembly (our .exe). points out in methoddef 18 (converted: 0x06000024) @ il offset e9. problem there no offset e9 in in method , method appears built-in method, not anywhere in our solution, of generated code in solution.

the methoddef 06000024 is:

method #5 (06000024)   	-------------------------------------------------------  		methodname: create__instance__ (06000024)  		flags     : [private] [static] [reuseslot]  (00000011)  		rva       : 0x00005dbc  		implflags : [il] [managed]  (00000000)  		callcnvntn: [default]  		generic   		type arity:1   		returntype: mvar!!0  		1 arguments  			argument #1:  mvar!!0  		1 generic parameters  			(0) genericparamtoken : (2a000004) name : t flags: 00000010 owner: 06000024  		1 parameters  			(1) paramtoken : (0800000e) name : instance flags: [none] (00000000)  		customattribute #1 (0c00006f)  		-------------------------------------------------------  			customattribute type: 0a00001b  			customattributename: system.diagnostics.debuggerhiddenattribute :: instance void .ctor()  			length: 4  			value : 01 00 00 00                                      >                <  			ctor args: ()  

this methoddef inside of following typedef:

typedef #5 (02000006)  -------------------------------------------------------  	typdefname: mywebservices  (02000006)  	flags     : [nestedassembly] [autolayout] [class] [sealed] [ansiclass]  (00000105)  	extends   : 01000005 [typeref] system.object  	enclosingclass : routedesigner.my.myproject (02000004)  

the actual method in il is:

.method private static !!t  create__instance__<.ctor t>(!!t 'instance') cil managed  {    .custom instance void [mscorlib]system.diagnostics.debuggerhiddenattribute::.ctor() = ( 01 00 00 00 )     // code size       32 (0x20)    .maxstack  2    .locals init ([0] !!t create__instance__,             [1] bool vb$cg$t_bool$s0)    il_0000:  nop    il_0001:  ldarg.0    il_0002:  box        !!t    il_0007:  ldnull    il_0008:  ceq    il_000a:  stloc.1    il_000b:  ldloc.1    il_000c:  brfalse.s  il_0018    il_000e:  call       !!0 [mscorlib]system.activator::createinstance<!!0>()    il_0013:  stloc.0    il_0014:  br.s       il_001e    il_0016:  br.s       il_001d    il_0018:  nop    il_0019:  ldarg.0    il_001a:  stloc.0    il_001b:  br.s       il_001e    il_001d:  nop    il_001e:  ldloc.0    il_001f:  ret  } // end of method mywebservices::create__instance__  

there no offset e9 in method, i'm confused on number of points:

1) application nothing webservices

2) routedesigner.my.myproject.mywebservices must generated class @ build time, doesn't exist in of solution files, generated/hidden ones

3) there's no offset e9 in method specified watson dump?

4) application works on dozens of customer systems , has done years...this system issue , it's fresh install.

 

we've run microsoft .net verification tool , of runtimes including 2.0 verified perfectly. in case, uninstalled runtimes , reinstalled them no avail. we've cleaned , rebuilt solution no avail. there 1 administrator account on server , using it. tried running exe run administrator option same result. we've pretty exhausted can think of, question masses is: have other ideas on how figure issue out?

 

 

my problem .dll in wrong folder.  it didn't make sense because applications looks in directory i originally had in.  but moved .dll 1 one applications root directory , fixed it.  not sure if @ all, maybe of install setting got jacked , cause reference misplaced. 

what had sort of similar. in our case, external dll reference had 7-ish year old vb6 assembly 3rd party vendor. old enough wouldn't support anyway, purchased newer version built on .net , magically worked again. no idea why of sudden broke or caused it, because application had been using exact same assembly file pretty entire 7-ish year period @ least works now.

that solution won't rest of you, unfortunately. :(
