Tested with opsi 4.0.1\\
Tested with opsi-winst 4.10.8 - 4.11.2.1

This is an old version of the official template for opsi-winst scripts.\\
For description have a look at the opsi-getting-started manual.\\
Do not copy&paste this script but always look for the newest version of the opsi-template product.\\
The opsi-template consists of 3 script files (setup.ins, uninstall.ins and delsub.ins).\\
The opsi-template scripts are existing in three different kinds: to install 32 bit software (setup32.ins), to install 64 bit software (setup64.ins) and to install mixed 32 bit and 64 bit software (setup3264.ins).\\
Here we show only the 32 bit version.
