Odd my laptop Windows 7 64bit runs it fine

I compile the software on a Windows 7 64 bit OS. I also test it in a Windows XP 32 bit virtual image.

The message of System Argument Out Of Range could mean a few things. Let me take a quick peak and see what I find that could be specific to your hardware configuration. You can try reinstalling. Also ensure you have the latest .net 3.5 framework updates.

DJ Sures thanks for quick reply I have tried to reinstall it and still the same, but the Firmware upgrade software works fine.... :/ btw I have the latest .net framework 3.5SP1 and 4 installed on both OS's..

Update: hmm.. I've found out that the problem occurs only on vaio notebooks. I have two of them at my hand and ARC crashes on both of them, however I have tried to run it under windows server 2003 and windows server 2008R2 on my server PC and also tried on my home PC that runs windows 7 32bit and ARC worked like a charm what a pity tired

DJ, could this behavior occur if your form is unable to populate the com port drop-down menu? I'm thinking Sony-specific software/drivers might be monopolizing resources...

radmeck, I was also thinking about the same, but yesterday I have tried to run ARC on my Acer Aspire One D255 netbook and it crashed, however it worked fine on HP and Lenovo laptops.. :/ Ooop... just during the posting of this message I have tried to install ARC under another Windows XP SP3 on my vaio laptop (wich is actually the XP Mode feature under Windows 7) and BAM! it worked!

Interesting......... I have 3 Sony VIAO laptops that I use. They are Windows Server 2003 32 bit, Windows 7 32 bit, and Windows 7 64 bit.

The firmware update utility uses the EZ-B SDK, and the COM Port list is populated by its public method. The Firmware Utility and ARC use the same public method from the SDK DLL. So if one works, so should the other.

I'm wondering if i'm dealing with a .Net bug due to the unmanaged interop calls for handling the joystick and video capture. Let me take a peek at the execution path and see if anything could be causing the crash.

Jeremy from Solarbotics has a 32 bit XP installation on a desktop that has occasional troubles with ARC. Every second or third install crashes and requires a reboot and reinstall. I haven't had time to investigate his machine to find the problem. Wether or not it's the same problem is unknown.

First, let me throw some detailed exception handling around some methods and publish another release. I'll make some time in the next day or two .. It's really too bad that you experience an issue with ARC. I put a lot of care into testing each releaes before it is published. They are tested on a XP and 7 in both 32 and 64 bit OS'.

hmm.. that becomes really interesting, cause when I run the Firmware Utility the dropdown list is not being populated, it's just empty.. so I see the problem is really in com ports..

btw.. in the mentioned above Windows XP where I was able to run the ARC, the dropdown list of Firmware Utility is also populated
