Installing assembly in GAC in Windows Server 2008 : Resolved

I developed an event handler and need to deploy it on production server. My production server is built on Windows 2008 Enterprise Server 64 Bit and there was only one installation on server i.e. SharePoint Server 2010. Now I need to install my assembly in to GAC. I copied my .dll to production server. Then I opened c:\windows\assembly and drag drops my assembly in to GAC (c:\windows\assembly folder). But nothing happened and my assembly couldn’t install in GAC 🙁

Drag and drop was not working. So second alternative was to use gautil.exe to install the assembly inside GAC but as it was production server so there wasn’t any installation of visual studio and hence there was no SDK installed therefore there wasn’t such exe like gacutil.exe. Again that was a problem. Now I worked on why drag and drop is not working. I searched here and there and follow some articles but nothing helped me. I disable UAC and restart server but it doesn’t work. I opened console and explorer using run as administrator but nothing helped me. Then I copied gacutil.exe file from my development machine to production server but I couldn’t run it (Though lastly this technique worked for me).So finally I resolved this issue and below are the directions for how to resolve this?

1. First check that if production server is of 32 bit or 64 bit?

2. If it is 64 bit then open folder “C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\x64

But if it is 32 bit then open folder “C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin

3. Copy 2 files i.e. gacutil.exe & gacutil.exe.config

4. Paste these files to any location of production server.

5. Your gacutil.exe is now ready to run and u can install assembly in to GAC using this small utility.

 Points to Remember

* When you drag and drop assembly in GAC it won’t give proper error messages (Like targeting framework error) if it has any so better to use gacutil to install assembly.

* gacutil.exe doesn’t run standalone rather it needs a configuration file to run i.e. gacutil.exe.config
