I am sure the sanguino is very clever but it's always been difficult. I think it needs an overhaul especially with latest tool chains and also the build instructions do not support long file names (missing double quotes around files).

That said Visual Micro should still support it. There have been a number of releases in the past week or so to handle problems associated with platforms that state an older tools version (or no version) yet a newer one is installed.

This situation was compounded with arduino 1.8.2 because it installed versions that were not listed in the indexes. They have rectified that but the newer releases of visual micro handle it better now so we should be much more robust.

What version of visual micro is installed? "Tools>extensions and updates>arduino ide/vm"?

Thanks

Ah sorry I missed the fact you installed manually and thought you had used the arduino ide board manager (which you can always do)

In your email you said this:-

boards were not installed properly from VM. there was missing directories and files, so i did it by hand and then it worked
 

Was it the digistump or sandrino packages you had to install manually from the zip before it worked or did you not get to test each individually?

Thanks

Thanks, I will try updating the SharpLibZip from Git. It's used for the unpack. It's strange because I installed the same toolchain okay.

One question. Can you confirm that in addition to digistump and snguino you were also installed Arduino AVR? The screen shot related to the arduino toolchain.

Thanks, was that avr 1.6.18?

@Lino : New thread created here for an "intellisense only" error report. 

@AnBe the latest update contains an update SharpZip library. I hope that solves any issues expanding the package zip,tar,gzip files etc.
