Sorry you're getting an error message. But what happens after it?
And since people post here internationally, it wouldn't hurt to ask, "What's your native language? And in which country did you download your trial version?"
I'm from Ireland. I downloaded the version in Ireland. My first language and the only language I use on this laptop is English. I have installed it with "International English" and then "North American English". No difference, still getting error.
I get exactly the same error and error text, using AE CS5.5 ob Windows 7. I also get an error saying
3468 <dynamic link><5> 000000001BA93B80
After the texts I get the oppurtunity to save the project (no need since it did not start) and the just quits. At the same time Photoshop also has given in, not being able to start that either . but there it is just an error saying Photoshop can nopt be started (hapooends after the second text in the startup saying "Initializing"
Yesterday I workd with both programs, closed all programs and the computer, but now when starting to work - this happends!
I just downloaded AfterEffects, installed as a trial, and get this error whenever I try to open the app.
I'm on Mac OS 10.7.3. This is AE CS5.5 (version 10.5.1).
I set the language to North American English, but according to an Adobe employee, the text of the error message has nothing to do with the error. (?!)
I tried uninstalling, re-downloading and re-installing, still the same thing.
So, not a very encouraging trial so far!
