I have (several) .Net application using the NationalInstruments.NI4882.dll which works fine with
- GPIB-USB-HS
- Driver version 3.02
- Windows 7
- .Net Framework 4.0
However, If I only install .Net Framework 4.5 (and nothing else has changed), the compiled program which previously worked fine, suddenly does not work anymore.
In the NI IO Trace it can be seen that only function IbWait does not work properly. It gives an EARG(4) error..
It seems to do an improper call "ibwait (GPIB0, 0x91300000)" instead of the normal "ibwait (GPIB0, 0x00000000)".
I have tried the latest driver version 3.1.2 also.. but it gives the same error.
Can any advise be given here ?
Greetings
