Error 16 in PS related to WIA Device Manager ?
I'm restarting a discussion about this issue which I have already reported last year in the PS forum. Still not answered...
Many of us have been hit by this problem after a CC update :
Please uninstall and reinstall the product.
If this problem still occurs, please contact Adobe technical support for help, and mention the error code shown at the bottom of this screen.
Of course, reinstalling doesn't help and the multiple "fixes" asking you to change a lot of permission settings for some Adobe folders don't help either. The only "fix" that works, is to run PS as an administrator. However, you may not want to do that. I decided to track down the problem more deeply and I eventually could spot the possible origin of the failure. Each time this problem occurs, I can see the following event appear in the Event Viewer, exactly at the same time :
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
to the user Photo\<User> SID (S-1-5-21-3830724593-899982153-72885144-1000) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.
Upon startup, PS obviously tries to activate the WIA Device Manager DCOM object (why ?) and this fails and crashes the application unless you have launched PS as an administrator.
Using Component Services I have given all possible launch and activation permissions for the WIA component to the user trying to launch PS (an administrator, by the way) but this didn't help. So I'm stuck for the moment.Thanks in advance.
