Required application access not granted during installation

To understand the capability requirements, the best way is to remove all capabilities and check the epocwind.out to see what capabilities are needed.

As for what capability is ok for self-signing, guess you should use the same advise you give on many threads..check the documents

A 'dir epocwind.out /s' is what it would take to find the file.

Anyway, when I do that it gives me this path : C:\Documents and Settings\[Neil]\Local Settings\Temp

Edit : sorry I didnt notice that you had more messages below the one I read..each one actually telling each step that you are doing

Edit 2: I believe you had already found your solution in http://discussion.forum.nokia.com/forum/showthread.php?t=131708&highlight=capability
Anyway..happy posting (Gosh I could have made 3 posts instead of editing the same one 3 times )

This message may come up when your installation file (.sis/.sisx) copies files to other application's private folder or trying to install files where it shouldn't. So check in that respect.

Issue seems to do with capability. Check on that issue.

Another possibility could be that you are trying to install a binary with a name which already exist on the Z drive.

Maybe you have another application with the same name installed (Thats what the installer might be saying)
Regarding capability, carbide 1.3 has got a capability scanner which might be useful to you (Note: I dont know if its available for all versions, but its available in my developer edition atleast)

edit : just noticed that you got codewarrior anyway info will always help!!
