"Unable to start Tag Monitor"

[Troubleshooter]

I just installed LV DSC 7.1. I was going through the demo examples. When I try to start the Tag Monitor, I get the unhelpful message, "Unable to start the Tag Monitor." I have tried re-installing the DSC module. I have tried repairing the DSC module installation.

Have you defined a .SCF file? see the attached image. tag monitor uses tag engine and your current scf file. I don't remember what happens when running DSC for the first time and what the initial scf file is.

Although starting tag engine and selecting scf file may be done programmatically, the example you are trying may have missed these steps. I suggest you give us more details about the problem and your DSC  scf and servers settings if the problem still exists.

I am using the HMISecurity.vi example in the labview\examples\lvdsc\security\HIMSecurity.vi directory. This is the first example you do in the boolket "Getting Started with the LabVIEW Datalogging and Supervisory Control Module." The .scf file that loads is "HMISecurity.scf [Demo]."

I should have added that the example vi runs. It executes without any error messages. It is just that when I want to use the tag monitor, there is a problem.

I also tried to start the Tag Monitor using the vi "Start Tag Monitor.vi." The error cluster returned was code = 6001, source = "Get Window RefNum.vi."

a real problem!

your explanations are quite clear, but I don't know the answer.

just a guess: do you have several copies of DSc on your hard drive? I mean using several different locations on your hard disk for reinstalling the DSC module each time you reinstalled that. if so, delete extra copies. I had had a similar problem sometime times later (but not quite similar) and it was solved by deleting duplicated files (note that this was a completely personal experience!)

"WIN Get Window RefNum.vi" is a building block vi of DSC. I think that there is a problem with your installation.

another Q: can you start tag engine separately? any error?

From the vi name it sounds it have something to do with registry key. Check if you have tag monitor reg key setup under National Instruments. If you do, maybe then you are not login as administator of the machine so you cannot access reg key.

The tag engine is up and running just fine.

I can not find any registry entries for the Tag Monitor.  I think the install is corrupt.  However, the installer does not seem to fix the install correctly.

Are you able to launch Tag Monitor from the menu? 

Tag Monitor is a separate utility.  I believe it's filename is tagmon.exe.   You can search for it on your computer and try double-clicking it.  Of course, the problem remains -- launching using the VIs, unfortunately.
