I reformatted my PC again, and I faced the same problem with opera, failure in loading launcher_lib.dll. And just after installing(wic); the 32-bit windows imaging component the prolem was fixed. So now I am sure that this software can solve this problem with opera.

This is not a patch, it's rather a windows software. You can download it using this link https://www.mediafire.com/?pdhswoonci991r6 or look for it on the NET.

Hi
That's me again, and Eureka
I found the solution. I was looking in some sites trying to find a solution for this problem. In a site they mentioned (wic), then I remembered that I have this component among the sotftware programs I save here. So I intalled it and it worked wonderfully. I could install Opera 20.0.1387.91.
I uploaded the file on mediafire so that you can download it easily.

Of course this is fore woindows 32-bit, if your system is 64-bit then you have to for it. Hope this will work for you. Good Luck

hi,
I am facing the same problem with opera. I don't think this has anything to do with the version of Windows. I am using XP3, and everything was working perfectly. I tried all opera versions: Opera 20, Opera developer, and Opera next. There was no problem installing them with XP2 or XP3. But since I reformatted my PC, I got this error: Opera failed loading launcher_lib.dll because windowscodecs.dll is missing. I tried DLL-files fixer but still not working. I am looking for a site from where I can download windowscodecs.dll. I hope I will find a solution soon. Now I am using Firefox, it's not bad, but it's just that I am used to Opera.
