Error running Testandifier on a plain DQMH module (LV 2022 32-bits, TS 2022 32-bits, DQMH 7.0)

Recommended Posts


I've got this error running Teststandifier

Created an empty project, added a DQMH Singleton module called Module 1 as default.



Error -2147221164 occurred at Class not registered
 in DQMH_TestStandifier.lvlib:TestStandify State Machine.vi->DQMH_TestStandifier.lvlib:Main.vi

This error code is undefined. Undefined errors might occur for a number of reasons. For example, no one has provided a description for the code, or you might have wired a number that is not an error code to the error code input. 

Additionally, undefined error codes might occur because the error relates to a third-party object, such as the operating system or ActiveX. For these third-party errors, you might be able to obtain a description of the error by searching the Web for the error code (-2147221164) or for its hexadecimal representation (0x80040154).

DQMH Module was validated before.

Hi Maurizio !

I've never seen this one yet !

The error seems to point onto an ActiveX problem.
Moreover,  the output shows that the PPL was built.
After the PPL is built, the TSifier tries to connect to TestStand to build the sequence file.
It seems that your TestStand API was not located / registered correctly.

Do you also have a 64 bit TestStand installed on the same machine ?
