Hello All,

I'm new here today

Using latest build of ATMEL Studio 6.1.2674 with SP1 and the VisualMicro plugin for Arduino...

I -often- see the following error when trying to build or enter 'debug'...



Compiling 'ArduinoEx1' for 'Arduino Nano w/ ATmega328'
Binary sketch size: 4820 bytes (16% of a 30720 byte maximum) (1.00 secs)
System.Exception: Visual Micro: Unable to save new program settings file

   at Visual.Micro.Visual.Studio.Arduino.AddInApp.CompileDo(Project oProject, Boolean IsDebugStartCommand)
   at Visual.Micro.Visual.Studio.Arduino.AddInApp.Compile(Project oProject, Boolean IsDebugStartCommand)


The problem will resolve itself after a while if I keep trying the same operation, or, try other buttons at random.

Any ideas?

You are quite correct. I don't.

I'll email the contents of the said file using the address we've corresponded on earlier.

Hi again.

I'm actually at work at the moment, so will give the suggestion a try later, albeit not a 'fix' 

My machine is a (Windows 7 Ultimate x64) Core I5 with 16Gb ram and a 3.4Ghz clock, so 'slowness' is unlikely, but the virus checker may well be holding up file open/close operations as you say.

Looks like you were right.
If I turn off the resident scanner, it works without fault.
So yes, vm is opening and closing the config frequently and getting tangled up with the scanner.
Thanks for the suggestion. Really should have thought of that myself. By 'trade' I'm a software engineer with over 35 years in the game. Silly how you can overlook the ******* obvious 

Not sure if this is supposed to be fixed yet, but I have the same issue.  I just this morning installed an upgraded version of Trend Micro, and got that rather cryptic message.  I didn't have the problem with the old version, ever: wonder why?  I found I had to close and reopen the sketch between each build.

It might help others to know it can be worked around by entering the sketchbook directory as an exception in the Trend Micro file monitoring lists.  Probably other virus software has a similar feature.  I suppose it opens a security hole, but I can't imagine it's too serious.

The Visual Micro version I am using in Atmel Studio 6.1 is 1.1309.11

Is there any update for this issue.  I just started using the Visual Micro plugin with Visual Studio 2010 and I am experiencing this issue the majority of the time when I try to build and pretty much every time I try to debug...even a little simple empty setup/loop sketch.   
If I shutdown VS2010 and restart I can get a couple of compiles but then I get the error consistently.  If I shutdown my antivirus I can get clean compiles but that's not a solution.

Thanks for posting your solutions, it's mainly trend that reports this issue. I don't hear about it from other virus checkers.
