Regular Rep: 4 Joined: 20 Nov 2004 Posts: 1,244 | I copied the instructions I wrote in another post in this thread http://www.moviecodec.com/topics/37173p1.html, with minor modifications for this particular codec. I hope you’ll forgive me for that.
Tag 7 is the “Microsoft CCITT G.711 (A-Law and u-Law) CODEC for MSACM” (at least that’s what the file description says). It’s been in all distributions of Windows from Windows 95 to XP (you may have to check certain options during installation in Win 95/98 to have installed though). It may have been removed in Vista - I’m not 100% sure.
If you tell me which version of Windows you’re using I could give you more detailed instructions on how to get it.
(I have steps for Windows 95 and 98 after this paragraph)
Here’s the steps if you have Windows NT 4, 2000, or XP:
Go to your Windows CD, and look for a file named MSG711.AC_ (it’s usually in the I386 folder). Copy it to your desktop. Then run the command prompt (start, (all) programs, accessories, command prompt; or start, run, then type cmd.exe). You should be in your home directory (C:\Documents and Settings\youruserid) if you’re on Windows 2000 or XP. Type “cd desktop” without quotation marks and press enter. If you’re using Windows NT 4, you should be at C:\ instead. Then type “cd C:\WINNT\Profiles\youruserid\Desktop” instead. Then type “expand MSG711.AC_ msg711.acm” without quotation marks and press enter. That creates msg711.acm on your desktop. Now copy that file to your C:\Windows\Sytem32 folder (if you have XP) or C:\WINNT\System32 folder (if you have Windows NT 4 or 2000). Next run the registry editor (click start, run, then type regedit.exe). Navigate to the key (“folder”) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32 Make sure Drivers32 is selected on the left pane. Create a new string (click edit, new, string value) and name it msacm.msg711 then double click it and for value type msg711.acm
(Quick) Steps for Windows 95 and 98:
Go to your Control Panel (Start, Settings, Control Panel), and Add/Remove Programs, then go to the Windows Setup tab. Double-click the Multimedia section. Chances are 'Audio Compression' is unchecked (meaning the codec isn’t installed). If that’s the case, check it and click apply. You may be asked to insert your Windows CD. There’s a chance it is checked, but still mis-installed; in that case, uncheck it and press apply, then re-check it and click apply.
If both methods fail, you can install the codec manually for Windows 95 and 98, but you have to get the msg711.acm file out of the right cabinet file and move it to your C:\Windows\System folder. Then you have to find system.ini in your C:\Windows folder, and add the line
MSACM.msg711=msg711.acm
under the [drivers32] section.
Preliminary searches yield that msg711.acm is in:
WIN95_08.CAB on the Windows 95A CD
WIN95_11.CAB on the Windows 95B CD
WIN98_50.CAB on the Windows 98 CD
WIN98_59.CAB on the Windows 98SE CD
