Can not open 7.1 program in labview 8.5.1 --> handler error

[solemes]

I made a program in labview 7.1

And I wanted to open it in labview 8.5.1, but it opens with errors, and I can not run it.

In every sub vi, till the lowest level, I got the error "handler error".

Can somebody help me?

You didn't do something silly like save VIs from vi.lib into an llb did you? If so, remove all of them from the llb and try to reopen the old top level VI. If you continue to have problems, post your VI.

Hi Sven,

Due to data dependencies within the *.LLB your 8.5.1 version of your vi was still opening the 7.1-version of the 'General error handler.vi'. Because these two version are no longer identical, LabVIEW concluded that the wiring you made was no longer correct.

Replacing the 'General error handler.vi' under the data dependencies with the one at: C:\Program Files\National Instruments\LabVIEW xxxx\vi.lib\Utility\error.llb

should resolve the problem as we discussed on the phone.

Kind Regards,
