MSVCR71.dll not found when loading Java applets in Opera?

Thursday, 13. November 2008, 18:15:48

After I began to use my old PC with a fresh install of Windows XP(since my Macbook is at Eplehuset getting some new parts, and yes, the PowerBook also died two days later). I've gotten a strange error message every now and then, and Java Applets refuse to respond. And yes! I hunted down the

and killed it!

Getting this error message when loading a Java Applet in Opera on Windows?

Solution
Close Opera, copy the file (MSVCR71.dll) from C:\Program Files\Java\jre6\bin\msvcr71.dll to C:\Windows\System\ (and of course you have to have Java installed).

Now you should be able to load Java Applets again

Get the latest version of Opera at www.opera.com
Get the latest version of Java at www.java.com

Update [May 31 2009] - A tip from Sanchit Karve. He wrote in the comments that you could instead of copying the dll file, add (JavaInstallDirectory)\jre6\bin to the Environment Variables. It's a better solution. Thanks for the tip.

New blog design! o_O

Strange. It should probably have been in the Java installer. We don't use VS 7, so the message is not from us. Feel free to send them a bug report though, and they will probably update their installer to copy the file there for other applications (like Opera) to use.

I'll file them a bug report

Seems like others also got this problem: http://www.duckware.com/tech/java6msvcr71.html

Strange issue.

No, it's NOT fixed. The fact is the user still has to repair this issue. Why does it even occur in the first place? Opera's such a fine browser. When will the problem actually be fixed, rather than requiring user intervention from users who feel uncomfortable intervening in the operation of their computing system?

(But thanks for supplying a patch. Grin.)

Copying the DLL file in the system directory is a bad idea.

Instead add (JavaInstallDirectory)\jre6\bin to your Environment Variables and everything will work fine.

Tried and tested with Opera 9.64/10a on Windows 7 RC

Finally!! Thank you Sanchit Karve! That finally fixed it! Stupid error... (Btw, should I really link to the 32-bit or the 64-bit version of java?)

Been having this problem when full-screening flash movies in Opera.
It worked fine, just gave the error anyway. Also possibly why Java applets had problems.

Problem fixed now. Thanks.

Adding the java bin directory to the path is a great way to solve this. You can also just add msvcr71.dll next to each exe that needs it.

However, for giggles, I made this launcher. You put it next to opera.exe and use it to launch Opera. (Only tested on winxp admin account though).

It just gets the java bin path from the registry and adds it to the PATH for the opera.exe process. This allows Opera to find msvcr71.dll .

Thanks man, pretty amazing that Opera developers hasn't fixed this problem yet. It's a very common problem among Operausers and occurs everytime u reinstall. Worst part is that when u try to browse Operasupport for useful fixes, u find absolutly nothing, zip, nada, on the subject?? What's up with these guys anyway? Are they falling in the same trap IE-developers has? Not listening to the users?

Thank you. This made java work for me in opera.

I was banging my head against a wall in frustration. I tried everything, reinstalling java, all the various trouble shoot guides, nothing worked. Both the java and opera official help pages were absolutely useless. I had to google for this, and randomly stumbled upon this page..
