When I try to launch Flowcode from Vista I get an error: Flowcode application has stopped working. This application has been installed for about a year. The error just started and I can no longer use the program. Tried reinstalling, same error. Any ideas?

Sounds a bit strange - has any other software or updates been installed onto your PC that could account for this error (e.g. could the installation of Vista SP1 caused this error)?

And when does the error occur - does it happen seemingly randomly, or does it happen after performing a certain action within Flowcode?

It may also help if you listed the version of Flowcode and the version of Vista you are using so we can try to replicate the error here.

And finally, we hope to publish a new patch today that will upgrade Flowcode to v3.6. Installing this may solve the problem for you.

Oh that's a good news !

What's the differents between the 3.4.7 ?

I have tried updating and reinstalling versions 3.4 and 3.6 on Vista home premium. Also, just to make sure, I restored my computer to a previous date.
The error pops up as soon as I try to launch the program. All I get to see is the splash screen.

I recently tried installing version 2 demo, and it works.

I really don't know what could cause this error. You can try a few tricks in Vista to narrow down the problem:

1) try running Flowcode in admin mode (right-click and select "run as administrator")
2) try running Flowcode in compatability mode (e.g. as Windows XP)
3) try turning off "Data Execution Prevention" for Flowcode (find this screen in "Control panel..System properties..Advanced..Performance..Data Execution Prevention")

Please let me know how you get on.

The one thing I did not check. It was the DEP. Thank You.

Thanks for letting me know the solution. I'll ask Ben to post a note on our FAQ site justin case others run into this problem.

Hi There
I just got a new laptop with Vista Home Basic on I have loaded flowcode V 3 but when I try to send my program to the development board it tells me that the USB cable is not connected. I have checked in my device manager and it see the development board as (Matrix USB PICmicro programmer) what can I do to fix this problem.

Hi Brian

The fix is documented here.
http://www.matrixmultimedia.com/support ... .php?t=507

To allow PPP to communicate with the USB programmer board you have to goto Control Panel -> System -> Device Manager. Then find the Matrix USB programmer under the USB section and double click it. Once inside the property page goto the power settings tab and disable the tick box saying allow windows to power down this device.

Thanks Benj
That worked like a dream, but I have another problem when I use a keypad it works perfect in the simulation but when I try to compile to hex or download it to the E blocks I get an error
C:\FlowCource\Get Phone Number.c(403): error: missing semicolon
C:\FlowCource\Get Phone Number.c(354): error:
If I go into C and look at line 403 it is the setup for the keypad and is as follows
tris` = (tris` | KPAD_ROW_MASK) & ~KPAD_COL_MASK;
can you please help me fix this problem
Regards
Brian
