Arduino and Windows 7 Problems

Since I’ve been fooling around with an Arduino in Windows 7 (64-bit if it matters), I figured I would share some tips to help get the compiler to work properly and the drivers to work.

First off, download Arduino .0017. If you run it, you will notice that it works properly, but graphical glitches exist in it. To get rid of these, download the latest JRE in 32-bit (even if you run 64-bit). Copy the Java folder from Program Files. Then, delete the Java folder in the Arduino folder and replace it with the one from your Program Files. This will fix it. (it’s possible that just deleting the Java folder from the Arduino folder will work; so long as java.exe is in your PATH variable)

Another thing you may encounter is that either the drivers don’t work properly or your computer hard crashes (e.g. no bluescreen, just a total freeze; can’t even move the mouse) after you upload a few times to your Arduino. To fix this, download the drivers from this page and install them:

There, I saved you the time I took to figure these idiosyncrasies out (e.g. the time I spent on Google). :-/

  1. Thanks for posting this JRE fix. It probably saved me several hours of searching and frustration.

    I have not had the VCP issue yet, but If I do, I know where to come.

    Happy Hacking!

  2. This post helped me alot!

    The latest Arduino 017 IDE does not have any graphic issues anymore. The FTDI drivers are still required, however.

  3. Hey.
    I a problem with Win7 64-bit too.
    I can’t find a driver for the USB Serial Port.
    This causes the ‘Serial Port’ entry in the Tools menu of the Arduino IDE to be disabled.
    Any help?

  4. Thanks for this information on the x64 driver. I just plugged my Arduino into my new system after leaving it in a box far too long and then realized I had a driver problem. Did a quick search and found your site near the top.

  5. Another thanks, I just googled ‘aruduino 64bit’ to get here because none of the beginners books even mention 64bit in their getting started sections (i’m looking at you ‘getting started with arduino’ by make magazine/oreilly).

  6. I did all the stuff you mentioned but still no response.
    When i click the ide icon …the first intro pops up …disappears then nothing. Not able to get the ide to work.
    I am ..of course …using the windows 7
    (reinstalled jave to 32bit and copied that folder to the arduino folder … nothing seems to make it work)
    Solutions please.
    Thanks :)

  7. Hi,

    When it came to getting the drivers to work I had tried everything except downloading 32-bit java and what not. It seemed like a hassle and I didn’t want to move things around. So what I decided to do was select the arduino folder rather then the specific subfolder where we were telling windows to look for the driver. I’m using windows 7 64-bit and I went into device manager and right clicked on the arduino (has to be plugged in to see it stand out with a yellow sign and an exclamation point) and clicked update driver. There I manually specified the whole arduino folder. That worked for me. Hope it helps for you.

    Anyone who doesnt know how to find the device manager you can type it in the text box when you click start or click the start button and right click the my computer in the menu and click manage. Good luck

  8. Thanks for the comment. I’m glad that worked for you.

    Neville: I’m sorry, but I can’t really support this anymore. I now have a Mac and do not run Windows 7 anymore. Possibly try upgrading to the latest version of the Arduino software if you haven’t already. I believe the bug is fixed in that version.

  9. I am getting this error when uploading any program to Aurduino Duamilanove atmega328 .

    Binary sketch size: 896 bytes (of a 14336 byte maximum)

    avrdude: stk500_getsync(): not in sync: resp=0x00
    avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

    I checked the port , driver.

    I am running windows 7 (64bit) help please .

  10. Thanks for sharing, my Win7 64 box has been freezing since I installed the shipped drivers.

    Uninstalled and reinstalled this morning and it seemed a lot better. Also running the ide in XP mode as admin.

    I’ll give the new drivers a bash later.

  11. Does not work for me. I am getting so frustrated with this. I just want to use it and it simply will not work, no matter what I do.
