LE7 is working properly with a limited user account. But it crashes at startup while "reading audiounit cache" when i try to open under admin account.
I tried to repair permissions etc... but i couldn't get it started.

Any suggestions ???

Mhmm… well…

I wonder how it has been installed. Did you install it under the limited account or under the admin account?

The crash may be related to:
- something wrong in the cache, trash it and restart
(in library/cache/com.apple.Components.LocalCache.AudioComponents)
- something fishy in permissions, try to repair them using the OS X instal CD (Apple drive utility in the install menu)

After that I'd try to trash everything from this plug then reinstall under the admin.

Thanks for the reply.

It is installed under admin account. Trashing and reinstalling didn't solve the problem !!!
I think there is something about permissions but i couldn't figured it out yet
I also tried the 7.0.1 update from apple site...
I can post the crash report. may be it helps to find out the problem.

Use an utility like Xray to look after the permissions the files have…

Are you sure your LE7 version is Logic 7 compatible?
