Crash on Client PC

I am getting the following error when WyUpdate runs on my clients Windows XP SP3 machine.

This is the information from the Event Viewer

EventType clr20r3, P1 wyupdate.exe, P2 2.6.14.0, P3 4ddcec0c, P4 mscorlib, P5 2.0.0.0, P6 471ebc5b, P7 3a63, P8 2c, P9 system.executionengineexception, P10 NIL.

Please let me know if you need more info etc to trouble shoot this issue.ThanksM

First, use the latest version of wyUpdate (2.6.16.4, not 2.6.16.0). Next, after you've given the user the latest version, tell me how you're calling wyUpdate. What arguments are you passing in?

Also, are you using the .NET 2.0 or the .NET 4.0 version of wyUpdate?

Why is my WyBuild not picking up that there is an update then? The first thing I did was run an update check and it says its up to date.

I'm a bit confused. When is the crash happening? If you check for updates and there's no updates (and no crash), then when are you getting a crash?
