Problem with Windows 7 and discovery tool

We have been using Nano Station 2.4.and 5 gig for a couple of years in our wireless network. Re-issuing radios using the discovery tool or trouble shooting has worked well on our lap tops with XP. I recently got a couple of new computers one with Vista and the other with Windows 7 and I can't get them to run the program for the ubnt Discovery tool. I get error messages.

"can't find javaw" etc

We can reset the radios to default or hopefully get the static ip for our customer from our office. But it is better to scan for it and save time. Xp is going away.....I would sure like to figure this out.

Thanks

Re: Problem with Windows 7 and discovery tool

Did you install the Java Runtime Environment?
If you can read this, you're too close.

Jumping in with the same problem...yes, I just re-installed Java Runtime Environment on my Windows 7 64 bit system, Java version 6 update 31. ubnt Discovery tool v2.3 appears to be looking in C:\Windows\System32\cmd.exe
Suggestions? Thanks, Yooper

Re: Problem with Windows 7 and discovery tool

I run the discovery tool all the time on this laptop (Win 7 pro 64bit).

No probs what so ever.

Make sure you are running the .JAR file not the batch file that is also included in the UBNT download.
If I run the batch file I get the "can't find javaw" error along with W7 briefly opening the command window.

Re: Problem with Windows 7 and discovery tool

I find the tool is bugged out on win 7 64 bit.

 

When I scan it shows 38 devices a few seconds later it shows 47 devices and 2 secs later it shows 48 devices.  EVERY TIME.  Once and a while it will stop at 47.

 

If I run the tool on a laptop connected via wifi or lan I get 55 devices with in a few seconds every time.

Same on a win server 2003 /32 bit.

Save a window. Run your Ubnt software on Linux!!

Re: Problem with Windows 7 and discovery tool

I get the same - i put it down to basically the time it takes for the packet scanning to take place.

Works find on win7 64bit for me - its probably only designed to find one device at the other end of your ethernet cable or devices on a small network.

Re: Problem with Windows 7 and discovery tool

Hi everyone:

 

Please review the ShortCut TARGET value. Edit and point to where JAVA is being installed. As per recent version of this response on a Windows 7 x64 OS the values below worked fine.

 

"C:\Program Files (x86)\Java\jre1.8.0_25\bin\javaw.exe" -jar "C:\Users\IT.CAPPS\Ubiquiti UniFi\lib\ace.jar" discover
