Video not available, cannot find 'vids:iv32' decompressor

- We are an ISV.

- Our app plays AVI files in an MCI window, and works correctly in all
previous versions of Windows

- With Vista Beta 2, video does not play at all.

- The video playback window shows error message "Video not available, cannot
find 'vids:iv32' decompressor".

- Will Microsoft fix this?

- What is the workaround for now?

Workaround:
1. Copy ir32_32.dll from a WinXP machine to c:\windows\system32
2. Execute the following .reg file:

;---------- begin .reg file ------------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"vidc.iv32"="ir32_32.dll"
;-------------- end .reg file --------------

Try downloading the DivX codec - might help, might not. Either way, report
this to Microsoft :o)

DivX only plays DivX. IV32 is Intel Video 3.2. =)

Vista does not to my knowledge include the Intel Video codecs and to the
best of my knowledge will not be including that. As has been the case in
the past, if you want to use codec YYYY, you would want to provide the user
with codec YYYY.

I would probably recommend against using IV32 in your application - I
believe the code has been bought by Ligos from Intel, and they could
probably provide you with a redistributable decoder that your users could
use if you wanted to continue to do this.

I was able to simply do the regedit, since ir32_32.dll was already on
system32 on my HP Pavilion ;)laptop . Thanks for the hint!
