This is ticking me off. I've tried THREE TIMES to download, I restarted the entire computer, and I STILL can't play anything. I even uninstalled the previous plugin and I get nothing.
Oh, I use Google Chrome and I have Windows 7.

Thank you so much vanelan and Max Maxter! Your advice solved my issues.

Thanks Mad maxter (and others with the solution) - the plugin wasn't being found until I tried your fix - now to get gaming!

Hey just a minor issue I've been having when using Vizzed like a lot of other people, I couldn't play the games because it said the Plug In wasn't found so I uninstalled the Vizzed Retro Game Room. But since I was using Google Chrome I noticed through earlier posts that this was an issue restricted to Chrome, I downloaded Firefox instead, but every time I try to download to Vizzed Retro Game Room again it only downloads about 75% of the way and doesn't complete, it just sticks and doesn't go any farther. I've restarted my computer and done the process an excess amount of times and tried the other version and it has the same results which is affecting my ability to play games on the site. Is anybody else having this issue or know of any way to resolve this?

Thanks guys. First post from myself

Hi Everyone, I seem to have a similar issue as everyone else. I downloaded the plug in through Chrome and firefox, I restarted the computer a few times and nothing. Every time I try to play a game, the message is "no plug in found".
Please help :-)

@LAURINA I think you might have to try reinstalling or C++ Run time. I think I reinstalled it and it worked. Then again, I don't remember how I did it.

Anybody having a tough time using save states without having the entire plugin crash frequently?

So here is the deal trying to download the plug in and it keeps giving me two error codes and they are 2503 and 2502 please tell me how to install this plug in please

coolerz261 : Go to thread (plugin not found) and there you will find the solution about this problem, have fun my friend !!!

i downloaded the new version of vizzed rgr and the c+++ and its still plugin not found. I'm using Firefox on windows 8. if you guys can give me an advice or send me a link to a thread that could help me, thanks for sending me a message.

I can't download any Dreamcast games, can anyone help me?

coolerz261 : Can you give me a little more information regarding the error message you are getting when you are trying to install? That would help give some insight as to the problem you are having.

asdren : His problem isn't what you are referring to. Please be sure you are clear as to what their problem is before handing out advice. That way people don't get confused/frustrated.

abigael : Are you sure that you not only downloaded the installer, but RAN the installer as well? You have to double click the installer to run it in windows, not just donwload the file. This is a pretty common mistake among users. Also Have you tried a different browser to see if you have the same results?

Exodiac47 : Are you getting an error message, or are the games just not loading? What is the specific problem you are having? Reason I ask is because NULLDC requires a controller to be plugged in to work correctly.

Jordanv78 : When I try to play a Dreamcast game, it says "starting ROM download" and it hangs on that message.

Davideo7 : I have downloaded the retro game room plugin multiple times and it still won't work. also how do you play playstation games

For some reason, the plugin stopped working on Chrome a while back. I assumed that it was due to a recent automatic update from Windows, but it seems to work on Firefox just fine (with the exception that I can't log into the site from there).  Until this happened, Chrome was the most reliable method of using the plugin, since Firefox often disables keyboard controls and I doubt it would accept controller support. 

Do you think it would be possible to fix this? Is there any way I can get Chrome to support the RGR plugin again? HELP. ME. 

game4brains : Your very welcome person because a couple days ago a tutorial of how to make it work was posted here is the link to it :3

Davideo7 :
I just downloaded the installer and ran it, and when I try to run a game, it says the plugin is not found. Help! 

Thanks man, you're a lifesaver! 

Well now it says I need a Beta Test Ticket to play.

Exodiac47 : To play Dreamcast games, you do need that.

Chetey : Broswer? And do you have VC++?
