Problem to run executable in windows 7 64.

[Malanar]

I developed an application using labview 8.5. Created an executable from it.

In windows XP i installed the labview runtime engine 8.5 and visa runtime and my EXE worked fine.

Tried the same on windows 7 64 and my application hangs the PC, tried the latest visa runtime with no success.

I basically uses a serial port (com 1) to comunicate witha device.

Tried to run it as windows xp compatible, same problem.

Any ideas?

Don't know why it fails in xp mode (except 8.5 is not supported under windows 7) but you of course cannot run it in windows 7-64. You need a 64 bit version of LabVIEW installed in a 64 bit OS and create the application there. For this you need to upgrade your version of LabVIEW.

Wasnt trying in xp mode but xp compatible, the property you get from the right click on the EXE file.

Anyway, i will try to download the 64 version of labview and port my application to it.

Can i choose if the application will be 64 or 32 or i need both labview to build to both types?

Hi Malanar,

32-bit LabVIEW (including LabVIEW-built applications) is definitely supported on 64-bit Windows 7, but official Windows 7 support started with LabVIEW 2009. Is the version of VISA you installed compatible with Windows 7? See these links for more details: LabVIEW 64-Bit vs. 32-Bit Applications FAQ and National Instruments Product Compatibility for Microsoft Windows 7.

Thanks for the reply.

Here is my setup:

the runtime for labview  -  LabVIEW85RuntimeEngineFull.exe

the visa runtime - visa501runtime.exe

and windows 7 64

The application was developed on labview 8.5

According to this URL (https://www.ni.com/en/support/documentation/compatibility/09/national-instruments-product-compatibil...), the minimum versios of VISA is 4.6.

And checking your FAQ link i got this:
Q. Can I run an executable built with LabVIEW 32-bit on a 64-bit PC?
A. Windows can run 32-bit executables on a 64-bit PC. Therefore, the LabVIEW 32-bit Development System, Run-Time Engine, and executables can be run on Windows 64-bit.

I can send the file, its a stand alone executable, just click and run, no installation required.
