Hi again.
I have tried installing in compatibility for older versions of windows. It is what the compatibility troubleshooter tries to do. As said it didn't work - windows simply blocks it as soon i double click the files - but thanks for your advice.
When i was running the beta 7100 build i used a specific procedure to get the logitech application work. And it worked perfectly. Think it was posted on the Logitech forum. It specifies to use a specific version of the quickcam software, so i haven't downloaded it from the logitech main site, but found a link via google to the specific version.
Here is the procedure:
"Firstly main culprit is service "Process Monitor" or "LVPrcS64". According to Logitech this service is responsible for Video Effect. By disabling that service from auto starting, all become stable; including main application, but you will have to sacrifice special effect.
Now the steps:
1- Download drivers version "quickcam_11.9.0.1263_x64.exe" from here :
Logitech QuickCam Software 11.9.0.1263 WHQL Windows XP x64/Vista x64
<http://www.opendrivers.com/driver/290374/logitech-quickcam-software-11.9.0.1263-whql-windows-xp-x64-vista-x64-free-download.html>
This drivers are for following models only: Ultra Vision, Fusion, Notebooks Pro, Orbit/Sphere MP, Pro 5000,Notebooks Deluxe, Communicate STX, Pro 9000,Pro for Notebooks, Communicate Deluxe, Orbit/Sphere AF,S5500,S7500, E3500. For other models driver/software may or may not work I did not try.
2-Right click and press "Run As Administrator" accept license agreement and press "next"
3-Program will ask u to connect webcam which you do
4-message appear "Camera Detected" wait
5-message appear "check for update" click "ask me again later" press "next"
6-message appear "custom install" click "software and drivers" press "next"
On this point installation will commence and u will have first Windows Explorer crash click Restart Program shortly after u will have second Windows Explorer crash, with everything on your desktop vanished, click again Restart Program and Logitech installation will finish, with your camera working.
7-Press "next" it will go to mic config press “next" again and finally u will have "Congratulations" The installation and setup is complete! Press "Done
Quick Cam Ribbon will appear close the ribbon.
Now, even thou installation appears to be successful you are still left with empty desktop.
DO NOT RESTART PC at this point, otherwise you will end up with big problem as described in "Oblomow58" post , do following:
8-press simultaneously " Ctrl+Alt+Del" choose "Start Task Manager"
9-on the top choose "Services" and bottom right press "Services" again
10-Services window will open. Stroll down and find "Process Monitor"
11-Double click on it, in the general window press "stop" in order to stop service, then change startup type from Automatic to Disabled, press "Apply"
12-Close all the windows and once again press " Ctrl+Alt+Del" ,this time choose to restart pc.
Upon restart your Logitech application and ribbon will work fine allowing you to do adjustments, exept special effect. "
