Hi,

Thanks for your quick reply.

I have changed my Sketchbook to c:\users\Roland\documents\Arduino

I have compiled and uploaded the program QRPNano (which has always worked fine) with the Arduino IDE without any problem.

When I try to compile it with Visual Studio I get the following messages:

ide.versionLTEQ=149
ide.exe=arduino.exe

I do not understand what goes wrong. It used to work fine before I did the reinstallation with the latest releases.

I would appreciate your help.

Thanks in advance

Roland

Hello,

Good news !!  It works  !!

I have compiled and uploaded a few sketches with core libraries and they uploaded without any problem.

I have stored my (homemade) user libraries on an external disc during the installation period. Now i want to install them back so that i can run my good old sketches again.

Can you advise me the correct location ( file ) where i have to install my core and user libraries?

Please also answer my message concerning the Atmel Studio upgrades.

Hopefully we can start working again.
Your help is much appreciated.

Thanks

Roland
