How to take backup of Biztalk dll from GAC

Question

I have a biz talk dll(Microsoft.BizTalk.ExplorerOM.dll) available in GAC which i can see from the path C:\\WINDOWS\\assembly (file:///C:/WINDOWS/assembly) . I want to take backup of this dll.

I read few article on stack overflow and other sites, they suggested dll is available under C:\\WINDOWS\\assembly\\GAC_MSIL\\Microsoft.BizTalk.ExplorerOM (file:///C:/WINDOWS/assembly/GAC_MSIL/Microsoft.BizTalk.ExplorerOM) . But in my case I don't have any Microsoft.BizTalk.ExplorerOM folder under GAC_MSIL .

Whereas the folder exists for other dlls. Please help how can I manage to take backup of the dll.

Answer 1

Since you are not responding to the comment I made, I'm going to assume you are using Microsoft BizTalk Server 2010 .

I did a quick search on the C: drive using the good old command ' dir ' on a BizTalk machine, and this gave me pointers to two locations:

"C:\\Program Files (x86)\\Microsoft BizTalk Server 2010\\Developer Tools\\Microsoft.BizTalk.ExplorerOM.dll"

and

"C:\\Windows\\assembly\\GAC_MSIL\\Microsoft.BizTalk.ExplorerOM\\3.0.1.0__31bf3856ad364e35"

Note that you probably will not be able to access the second location using a Windows Explorer. Using the command prompt to access it, works just fine.

If you want to copy it from the GAC on the location, just use the copy command to copy it to your desired location.

Hope this helps.

Answer 2

As mentioned by others you haven't specified your BizTalk version (or more importantly, your Microsoft.BizTalk.ExplorerOM.dll framework version) so I will make some assumptions. You are looking in the pre .NET4 GAC (c:\\windows\\assembly), have a look in the post .NET4 GAC (c:\\windows\\Microsoft.NET\\assembly) it might be in there.

If not, you can extract assemblies from the .NET2 GAC by running the following cmds:

cd C:\Windows\assembly
attrib desktop.ini -s -h –r
ren desktop.ini desktop.ini.bak

You will notice that if you now browse to c:\\windows\\assembly that it's just a normal file structure, where you can copy files out as you wish. To put is back:

ren desktop.ini.bak desktop.ini

I believe that this will answer your question however, depending on your BizTalk version and how you have installed the assemblies, if you installed by running a BizTalk MSI then you should have an install path (default %ProgramFiles%\\Generated By BizTalk) which will contain all of the assemblies that you are after

Answer 3

You can use DOS command Copy at command prompt to copy the Biz Talk DLL.

Please route to the Biz Talk DLL folder using command prompt.

GAC folder path is - c:\\Windows\\Assembly\\GAC\\

Answer 4

they are located at C:\\Windows\\Microsoft.NET\\assembly\\GAC_MSIL

If you want to view the folder structure of the GAC in Windows Explorer, you can do this by using the registry: Launch regedit. Navigate to HKLM\\Software\\Microsoft\\Fusion. Add a DWORD called DisableCacheViewer and set the value to 1
