Hallo,
ich habe eine anwendung unter dotnet programmiert, die daten aus einer Excel-Tabelle ausliest und danach eine Textdatei erzeugt.
Das funktioniert unter windows XP + Office XP oder Office 2003 prima!
Nur hab ich es jetzt unter Windows 2000 + Office 2000 getestet (hat ein Kunde so) und hier bekomme ich eine Fehlermeldung.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

An was liegt das, ist das Office 2000 oder Windows 2000 und wie kann ich die Anwendung unter allen Systemen stabil laufen lassen?
Ach ja, auf allen Systemen ist DotNet Framework 1.1 installiert!!!
Bin über jeden Tipp dankbar!
