Missing dll - where to put it ?

StymiedMike · Jul 6, 2023

I have an Atari Arcade Hits CD which I copied to the HDD and everything works but an introduction video. It says “Video not available, cannot find vids:iv32 decompressor”.
This is on Windows 10 but Windows 7 also used to give the same message.

Not a big deal but I figured why not just add the missing file. I searched & appears “ir32_32.dll” is needed. I downloaded the file & put in the Windows/System32 folder per this link.
vids:IV32 decompressor ? - Matrix Games Forums

That did not work so I also put it in the same folder as the game exe folder but that didn’t work.

I read that the installed codecs are listed in "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Drivers32". However ir32_32.dll was not there.

Then I read that ir32_32.reg needs to be run so I did that & ir32_32.dll then showed up in the registry. But the video still does not play.

I can play the file in VLC which does say “Codec: Indeo Video v3 (IV32)”. I looked in VLC > plugins but did not find anything similar to what is needed.

Where should the dll be placed? If VLC is able to play the video maybe I need an updated dll for Windows 10. How can I figure out what VLC is using?

Thanks for any information.

Hi,

Its a 32 bits file, on a 64 bits OS the file should be on C:\Windows\SysWOW64

Thanks for the reply -

I found a few different versions of the dll and tried them all in the games exe folder & the system 32 folder but to no avail.

The SysWOW64 folder already had an ir32_32.dll file, the latest version I’ve seen. The folder also contains several other irxx.dll files and all from 2019 and I’m presuming these came with Windows 10.

I tried to copy my oldest version into SysWOW64 to see if that would work but I did not have permission to do so. I read how to get permission but so far have not had luck. Maybe that’s a good thing.

I did copy this newest version from SysWOW64 into the games exe folder & into the System32 folder but that did not work. IOW it's currently in 3 locations.

The Atari software supposed to be able to play from the CD-ROM & it does. For convenience I copied all the files to my D: HDD and play from there. There is a second introduction video which does work & MediaInfo shows it as
Format: Cinepak, Codec ID: cvid

Any suggestions what else to try?

Thanks for the information.
The link refers to a Wow6432Node registry entry which I do not have & this maybe for Windows 8.1 because they also mention that.
The link also mentioned Indeo is blocked as a security risk on Windows 10, which I also saw mentioned somewhere else.

The closest I have is "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Drivers32". However ir32_32.dll is not there.

Previously I ran "ir32_32.reg" and that put the dll in the registry. But how do I know which version was installed? Since it did not work I deleted it.

I then tried this method, after first putting the dll in the System32 folder.
"REGSVR32 C:\Windows\System32\ir32_32.dl".

But got this message:
The module "C:\\Windows\System 32\ir32_32.dll" was loaded but the entry-point DllRegisterServer was not found.
Make sure that "C:\\Windows\System 32\ir32_32.dll" is a valid DLL or OCX file and then try again.

All the games play & I thought it would be a simple fix to get a 12 second introduction video working. At this point I’ll just watch the error message for several seconds.

Thanks again for all your suggestions.

Windows 10 64 bits will have also the registry branch HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\...

I have the following files:

Read More:

KyoriAsh from PCGamingWiki PCGW Community says "This registry patch is to restore the Indeo codec functionality for Windows 10 and above." and "There are two codecs to be restored: iv32 and iv50".
Then he provides 4 files (2 for windows x64 and 2 for windows 32bit).

Given that you have windows 10 x64, you can run these two commands:

Code:

reg add "hklm\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /t reg_sz /v vidc.iv32 /d ir32_32.dll
reg add "hklm\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /t reg_sz /v vidc.iv50 /d ir50_32.dll

If you want to delete them later:

Code:

reg delete "hklm\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /v vidc.iv32 /f
reg delete "hklm\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /v vidc.iv50 /f

Thanks for everyone's help -

I did see the "Wow6432Node". Don't know how I missed it before.

I also came across 2 comments that said the codec was disabled in Windows 10 because of a security risk. It's not worth any risk just to watch an introduction video.
