Error during migration

HI,

I got the following error during migration:
[h=1]Internal Server Error[/h] [SIZE=12px]The server encountered an internal error or misconfiguration and was unable to complete your request.[/SIZE]
[SIZE=12px]Please contact the server administrator at admin@example.com to inform them of the time this error occurred, and the actions you performed just before this error.[/SIZE]
[SIZE=12px]More information about this error may be available in the server error log.[/SIZE]

[SIZE=12px]More information about this error may be available in the server error log.[/SIZE]

did you get more informations in apache or php logs ?

it is a trouble with the permission on the installation directory ( c:\program files
etmake ), I changed the installation to the root C:/ and works fine.
