Hi Alex,
thank you for your ideas.
The good things are, SIM shows no errors. Wasn't here a log for each MSI? The logs only show the web part.

The DLL exists in "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Altiris.ASDK.SWM"

There is a sample script "D:\Altiris\Altiris ASDK\Samples\Software Management\vbs\policymanagement.vbs"
Starting the script gives me the same error.
PS D:\Altiris\Altiris ASDK\Samples\Software Management\vbs> cscript policymanagement.vbs
Microsoft (R) Windows Script Host Version 10.0

Hi Jan,
Looks like issue may not related to license, but script unable to find correct references in GAC.
Can you check that "Altiris.ASDK.SWM" and it redirection policies exist in "C:\Windows\Microsoft.NET\assembly\GAC_MSIL"
And also it will be good to check if any related errors appeared in Log during installation.
Also you can try some sample scripts from "<Altiris NS folder>\Altiris ASDK\Samples", if those will work, or also raises some errors.
Thanks
AlexTH
