I just had the same issue and recieved the following error for a host of updates while using the Adobe Application Managert:
"There was an error installing this update. Please quit and try again later. Error Code: U44M1I200"
The following apps did not update:
AIR for Apple iOS support (FB)
Adobe Extension Manager CS5.5 Update
Adobe Flash Professional CS5.5 Update 11.5.1
Adobe Media Encoder CS5.5 5.5.1
Adobe® InDesign® CS5.5 7.5.2 update
Adobe Premiere Pro CS5.5 5.5.2
Photoshop Camera Raw 6.6 Update
When I ran the Support Advosor app, it came back with: "Inspection found an issue but cannot determine the cause or corrective action. Please contact Adobe Support for further assistance."
Would like some advice on what I should do next. Thanks.
When I got the error "U44M1I200" I beleived it was because the "Adobe® Application Manager" was already open when I selected updates from Photoshop's help menu. WHen I made sure the "Adobe® Application Manager" was closed prior to selecting "updates..." from photoshop I had no errors.
