.NET Frame work with NT-4

Dear All
Could anyone help me with this?

Application has generated an exception that could not be handled.

Click on OK to terminate the application.
Click on CANCEL to debug the application

Followed by another one as follows

Registered JIT debugger is not available. An attempt to launch a JIT
debugger with the following command resulted in an error code of 0x2 (2).
Please check computer settings.

cordbg.exe !a 0x88

Click on Retry to have the process wait while attaching a debugger manually.
Click on Cancel to abort the JIT debug request.

This occured when i'm about to deploy my application to another PC (win NT-4 SP-6).I installed redist1.1 to this PC.
Application works fine with my development pc win 2000
Please Help and Advise me

whcih framework version is on your development machine.

(he said 1.1...)

The debugger error is probably because you don't have a debugger installed on the target machine (you have only the Framework there correct?)

If I were you I would get someone to give me a development machine with NT 4.0 installed on it, and see if your project will build/debug on that platform.
