Hello, in home page of LS install we see
....
Not latest Service Pack {OS}
....
whey click at these links we see table with four rows:
Unnamed, Computer,Description,Date
This table is non informative, add row ServicePack.
Install of .NET, if not found in installed software ask user to download it from internet, or retry or install from local source - it may be hard to download 20 Mb.
In my topic http://www.lansweeper.com/forum/yaf_postst1533_Lansweeper-installation.aspx installing MDAC at Win 2000 solved the problem, so may be need check of os version and tell user prerequisites.
And need install for admins - full install at server, "Configuration" and "Connection tester" at sysadmin computers to work with database WITHOUT sweeping database.
