Hi.

I made an application in VB.net 2003 (Framework 1.1)

Someone has launched the app on his computer (Windows XP Professional SR2. AMD 64 X2 Dual Core Processor 3800+ @ 1990Mhz., 2GB of RAM, 250GB HD) and received this error:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I suspect it's a compatibility issue (Framework1.1 is for 32-bit). But how can i solve this ?
