Meetinghouse webcast doesn't work in Win 7 64 bit?

Even though I have installed the Windows Media Encoder and verified that it works every time I try to start the Meetinghouse Webcast software I get an error message saying that Windows Media Encoder needs to be installed.

I would try uninstalling Windows Media Encoder and the software and then reinstalling to see if that fixes it. Many users are using Win 7 without issue, but I'm not sure about the 64 bit part...

On a laptop running Windows 7 Professional 64 bit.

The Media Encoder would install and run without difficulty and the Meetinghouse Webcast software would install without error but would not run citing a need to install Media Encoder (which actually was installed). Uninstalling, reinstalling, running as administrator, running in compatibility mode, trying with the Media Encoder replacement, nothing would work.

Installing the software on an XP machine went without a hitch.

Firing up a virtual PC running XP in a shell on the Windows 7 machine also worked without a problem (I forgot to check to see if the Virtual PC was running 32 or 64 but I'm pretty sure it runs in an emulated 32 bit sandbox).

Therefore, I conclude that in my instance the currently released software does not work on a 64 bit Windows 7 machine. I speculate that it will have similar difficulties on a 64 bit Vista machine. And I've never met anybody who ran 64 bit XP so I doubt that would ever come up.

Solution: SLC is aware of the issue and I am told they are working on Webcast 3.0 - it is likely that the solution will not be fixed once and for all until that is completed.

The software is now available. Learn more by visiting the Meetinghouse Webcast Software Beta page on the Wiki.

Cheers,
Jacob

The beta (which requires Expressions 4 on Windows 7) crashes every time I click the start webcast button.

You need to use Windows Media Encoder 64 bit version, Then Web Cast should work fine. Or at least it worked for me. I know 32 bit Encoder works better for most things but Webcast seems to be looking for version to match OS. I have both 32 and 64 bit Encoder installed, but Webcast will only use 64bit on 64 bit machine.

No longer available. Only Expression 4 is available, in a free version that allows for only 10 minute clips at a time or Pro for $149.

I tried with the meda encoder 9 and it does not work, I will try the beta version out of interest!

The beta version worked a treat.
Need to work out how to cut out the in built microphone on the jvc video camera and use a seperate microphone. But the streaming quality was good.
It also worked for well over 10 minutes.

Can we get a yes or no on will MH webcast v3.0 work with XP and Windows Media Encoder 9?

Will the free version of Expression run longer than 10 minutes every time?

Does MH Webcast v3.0 REQUIRE Expression 4 Pro ($200) to run?

Hi Arlan,

No, MHWC 3.0 does NOT require Expression 4 Pro-- Just the free version. There is no time limit on how long it can stream for.
