TYPO3 Core

When i want to import a t3d file with dependencies on extensions (for
example realurl) in the BE of TYPO3 version 4.5.X. Then i get the message:

"Before you can install this T3D file you need to install the extensions
"realurl". Clicking Import will first take you to the Extension Manager so
these dependencies can be resolved."

And when I click Import to import the extensions, I get the following
error:

"Not Found

The requested URL /typo3-4.5.7_temp2/typo3/sysext/em/mod1/index.php was
not found on this server."

For the TYPO3 version 4.4.X it will works fine.

Best regards,
