Export as SUU fails

Hi, 

When i try to export Windows bundles to SUU, either as directory or iso it fails.

I have the latest version 730 plugins installed, both 32 and 64 bit.

I'm using newest repository manager 1.7.0.158.

The directory where it exports to is created correctly, but nothing more happens, it just reports "Error occured" while preprocessing the job.

It does not get into the Job Queue.

I can without any issue export linux bundles.
