This page describes some technical problems starting and running .Net programs.
Program does not start at all
This error can have two known causes: .Net Framework not installed or Wrong Compatibility Settings.
.Net Framework not installed
You will most probably get an error message saying: "Mscoree.dll Could Not Be Found"
.Net Framework 1.1 or higher must be installed at the computer.

More information:
• Open the Add/Remove programs window this way: Start > Settings > Control Panel > Add/Remove programs
• A list similar to this will appear:

Control Panel
(Screen dump from Windows 2000. Other Windows versions look similar. .Net Framework 1.1 is installed here.)

Get .Net Framework

  Wrong Compatibility Settings
You will most probably get an error message saying: "CLR Error:80070002 The program will terminate now" or something similar. This has been reported on WinXP systems only (Thanks René).
Check the program compatibility settings:
• Right click on the program executable file (.exe) and select the tab Compatibility.
• ALL checkboxes on this tab should be kept unmarked.
All program files (incl. the executable) are by default installed to a subfolder (named as the program itself) to the Program Files folder at your system's primary hard drive (mostly the C:\ drive). The Program Files folder may have localized names, e.g. Programmer (in Danish).
