Install ASDK 1.4 on standalone Deployment Solution 6.9. This product requires NS ?

Hello,

We use a standalone DS 6.9 SP6 server. We are happy about the product. I'd like to create some custom tools using ASDK 1.4 for Deployment Solution 6.9

However when I run the excecutable altiris_asdkserver_1_4.exe file from http://www.solutionsam.com/solutions/6_0/ on the deployment servers the installation stops with error "This product requires NS".

How can I get it round ?

Thanks

Tomasz
