Indeo Video IV50 on Windows 7 Fix
Running into unnecessary problems trying to play a movie encoded with the accursed IV50 codec? I sure did. Some of my AVI videos were encoded with the Ligos Indeo XP Video codec awhile back via Pinnacle Studio 8.12.7, and has since stirred up a fuss trying to let me access them in Windoze 7. After much scouring the search results and tinkering and testing stuff, I believe I finally have that gremlin drawn and quartered.
First and foremost, you will need the Ligos Indeo Legacy Package (IV31, IV32, IV41, IV50, YVU9), which I believe is freeware according to my source. It will install Indeo Video codecs for 3, 4, 5, and Indeo Raw (YVU9). The filesize should be about 2,068,266 bytes. You can get it at...
Indeo Codecs Legacy Package (IV31, IV32, IV41, IV50)
Once installed, incredibly enough (believe it or not) you may still run into problems opening your IV50 encoded video. Why? That's because the Indeo installer FAILED (tch! tch!) to register the dll on Windows 7! Is it Indeo's fault, or WINDOZE SEVEN's fault, or BOTH? Who knows? Who cares? OK, I do, but that's a debate for another time. Right now I am itching to share the solution for the good of all mankind.
So go ahead and click that round Microsoft thingy at the bottom leftmost part of your desktop. Then click on All Programs followed by Accessories. Look for Command Prompt and right-click on it. Then click on Run as administrator. Helloooo, are you paying attention there? There's a reason why it's ITALICIZED and BOLDED! I cannot stress enough how *VERY* important this Run as administrator priviledge is, which is a very common problem in Windows 7 with some programs. Ignore it for this instance, and you will be smacked with a pop-up window out of nowhere happily informing you that "... the codec was loaded but the call to DllRegisterServer failed with the error code 0x8000ffff".
Assuming that you had followed the given instructions right down to the letter, you should be idling at the command prompt right now. Go ahead and type in the following:
regsvr32 ir50_32.dll
Press your Enter key, and voila, *hopefully* your problem should be solved. I know it did mine.

What about on WINDOWS 7 64 BIT? It doesn’t work for me.
Are there Windows 7 64 Bit instructions?
Please Help!
Thank you!

Thanks a million. I’ve been looking for over 5 years for help to open/view these video clips. Some of them are of my late father and grandmother and they were in this format only! It has been wonderful to be able to go down memory lane and be able to share them with everyone again.
Know I need to look for something to convert them to another format before I lose them again
Once again thank you very much!

Win7-64
The above didnt install so i just downloaded the “ir50_32.dll” from the net. Put it in “C:\Windows\System32″ and do the “regsvr32 ir50_32.dll” in a (Run as administrator) DOS prompt. viola it works – thnx to the OP.

Whoa, it worked for me too! Thanks so much! After installing the codec I used the fantastic crap-tatic encoder Super to convert my old videos to a more standard format. Geez, you’d think VLC would read these old codecs. I guess it’s legal IP issues which prevents VLC from support these tired old codecs.

I figured out that if you run the exe file with administrator privilages, from the start, it will successfully register the codec for you. Just right-click the exe file, and select “Run as Administrator”. I’m using Windows 7 x64 and it works great. Hope that helps.

I have tried all the steps as written, and nothing has worked. no idea what i’m doing wrong. and i’m not sure that the ir50_32.dll is the authentic one required to play the videos right. any ideas? i’ve tried many things

oh, and i’m using Win 7 x64 Pro…

It worked great on my Win 7 Pro x64… once I issued the following command immediately after reaching the C: prompt:
cd \windows\syswow64
Then I typed the regsvr command line.
