Hello,
thanks to you the package is now working.
Thank you for your help.

Hello,
WAPT 1.5 server on Debian 9.4.
Technical workstation on Windows 7 x64.
We need to renew the WSUS IDs so that all workstations appear in the console.
We found a script for this:
@Echo off
if exist %systemdrive%\SUSClientID.log goto end
net stop wuauserv
net stop bits
reg delete ...

Hello,
indeed, some of the directories and files in the package contain special characters.
The new configuration file resolved the issue, and the package is now working.
Thank you very much for your help.

Hello and thank you for your suggestion.

And otherwise...

Hello,
WAPT 1.5 server on Debian 9.4,
technical workstation on Windows 7 x64.
The first two package creations worked fine, but on the third, I get an error during the build-package command (same error from PyScripter). It's an empty package being created (wapt-get make-group-template tis-winrelais...).
