Remove 10.0 .NET SOE from machine with 10.2 server

[FilipKrál]

Hello,
We have a server that has been upgraded from 10.0 to 10.2 but one server object extension was not removed before unistalling 10.0.

Is it possible to un-register this server object extension (a single .dll) now that we are on 10.2?

I tried running the following in cmd.exe:

"C:\Program Files\Common Files\ArcGIS\bin\ESRIRegAsm.exe�?� /u "C:\WatershedSOE.Manager.dll"

but I get a message complaining about missing dependencies:

Unregistration failes. Could not load file or assembly 'file:///c:\watershedsoe.manager.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Any, hints welcome.
Filip.

(Sorry for duplicating, originally I posted similar question into a thread about Java server and I realized most people who could answer it won't see it there.)

What happens if you open a CMD prompt using "Run As Administrator" using either of the following?

cd c:\windows\system32
regsvr32 -u C:\WatershedSOE.Manager.dll

cd c:\windows\SysWOW64
regsvr32 -u C:\WatershedSOE.Manager.dll

Also, have you already upgraded ArcGIS Desktop to 10.2?

Hi, thanks for your reply; unfortunately in both cases I get:

The module "c:\WatershedSOE.Manager.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:\WatershedSOE.Manager.dll" is a valid dll or OCX file and then try again.

I found three entries that have 'WatershedSOE' in them in the registry, each with a CLSID entry underneath:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WatershedSOE.WatershedSOE
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WatershedSOE.ArcCatalog.WatershedPropertyPage
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WatershedSOE.ArcCatalog.PropertyForm

Does it make sense to remove these manually or will it just create more problems?

Manually editing your registry settings should be done with extreme care and not before taking a backup.  In most cases, I wouldn't recommend editing the registry unless you are absolutely positive there will be no negative downstream effects. 

When you tried unregistering with the ESRIRegAsm.exe application, was it a 10.0 or a 10.2 ESRIRegAsm.exe executable?  If the registration was initially performed with a 10.0 executable, then perhaps the unregistration process must be performed with the same version.  That is the reason I asked earlier if you had upgraded your desktop software from 10.0 to 10.2 yet.

EDIT: Can you try this real quick?  regasm c:\WatershedSOE.Manager.dll /u
The regasm.file can be found under the .NET framework directories; for example: C:\Windows\Microsoft.NET\Framework\v4.0.30319.  Try the command above using the regasm.exe under a 4.0 and a 2.0 .NET folder.
