Logitech 400 Pro problem

  muddypaws 10:17 09 Sep 2013

I haven't used this cam for a year or more, but used it yesterdayt.

When I now record a video clip and try to open it I get the message:

" Unable to open C/xxxxx for editing. The specified file is invalid or the MCI device failed to open the video".

I completely un-installed the software with Revo advanced option and re-installed from the original CD and updated from

Logitech. I still get the error.

Is this a Logitech software error or a PC one.

XP Home Sp2.

Any help please before I buy a new one!

My mistake it is SP3.

Which program are you trying to open the video file with?

It should open with the Logitech software, but no idea what it requires.

I have just looked in the Logitech 'Image Studio' folder on the PC and have found that the thumbnails will open with: Real Player/VLC /Divx10 and Arcsoft Digital Theatre.

Unfortunately if I select any one of those to 'always open with' the clips still don't play from within the Logitech window.

Apologies for late reply have been out getting wet!

After re-installing and updating again all seems to be working as of old.

Will resolve.. Thanks for your input.
