Error launching the 'LabVIEW.A​pplication" ActiveX automation server [Error Code: -18001]

[Berezka]

Hello,

I have TestStand 2010 and LabVIEW 2010 development systems.

In the TS LabVIEW adapter is configured to use Development System.

Till today everything worked properly.

Today I tried to run TS sequence (which worked yesterday) and got error -18001.

I changed LV adapter configuration to use LVRTE and then back to Development System - and got error -18001 again.

Please see the image below.

LV2010 development system exists and I can use it: edit and run VIs.

How can this problem happen and how to resolve it?

Thanks in advance!

Cheggers, thanks for reply!

I already solved this problem. There was something wrong with registry permissions. Probably, I changed it today by mistake, while trying to solve a problem caused by another program. 🙂

Fortunately you remembered your registry changes... else it would not be easy to troubleshoot 😉
