Error 1498 when attempting to build Installer

[nikvl]

Hi all, 

I managed to build an executable sucessfully l but received the following error 1498 when trying to build an installer:

Possible reason(s):

LabVIEW: (Hex 0x5DA) Library has errors. Fix the errors before attempting this operation.

Complete call chain:
Get LV Class Default Value.vi
AB_UI_Initialize_Framework.vi
AB_UI_FRAMEWORK.vi
AB_CreateNewWizard_Invoke_CORE.vi
CDK_CreateNewWizard_Invoke.vi
CDK_CreateNewWizard_Invoke.vi.ProxyCaller

LabVIEW attempted to load the class at this path:
C:\Program Files (x86)\National Instruments\LabVIEW 2018\vi.lib\AppBuilder\IB_Classes\Installer\UI\AB_UI_Frmwk_Installer.lvclass

I don't quite understand why or what is causing this error? Is it due to the subpanels (I used Call by reference)? I placed the SubVis as always included in the build though.

Thanks

First thing I'd do is to empty the installer destination path, if you already did a build earlier. Sometimes LV has a hard time dealing with things in the directory, and gives weird errors. Can't quite put my finger on it, but it happens to me regularly. Rebuilding the executable before retrying the installer, just to be sure, won't hurt.

Were you able to resolve this? Facing a similar issue.

I am experiencing this same error using LabVIEW 2024.

Possible reason(s):

LabVIEW: (Hex 0x5DA) Library has errors. Fix the errors before attempting this operation.

Complete call chain:
Get LV Class Default Value.vi
AB_UI_Initialize_Framework.vi
AB_UI_FRAMEWORK.vi
AB_Create_Build_Application.vi
EBUIP_Global_OnCommand.vi
EBUIP_Global_OnCommand.vi.ProxyCaller

LabVIEW attempted to load the class at this path:
C:\Program Files (x86)\National Instruments\LabVIEW 2024\vi.lib\AppBuilder\AB_Classes\Build\UI\AB_UI_Frmwk_Build.lvclass

I checked the filepath and that file is definatly in there, so I dont know why it is complaining

Is this happened with your particular project or with any other "empty out of the box"?

Try to build project from the attachment. Same error?

Starting with a blank project and minimum for working VI (while loop with a bool control & indicator) exact same issue.

Then it is a time to reinstall LabVIEW completely, probably. I installed 2024 three times so far on both Win10 and Win11 and haven't any issues from this side.

Technically this is a very low level error occurred in Get LV Class Default Value.vi, where the error code returned from call of the function LVClassDefaultInstanceFromPath from LabVIEW.exe in attempt to get defaults from the class. Theoretically you can "cut" this error in "\LabVIEW 2024\resource\Framework\Providers\Builds\AppBuilder\AB_UI_Initialize_Framework.vi":

then build will be continued, but there are no any guarantees on success after this, but you can try before full reinstallation from the scratch.

Tried reinstalling LabVIEW - No change.

Tried modifyinng the .lvclass and got this error while opening it:

I found the VI you posted and added a remove error where you specified, now have this error message:

That's a vi.lib\xml dll.

Can you open (run) NI_XML.lvlib:New.vi (In palette File IO\XML\XML Parser)?

If not, that is the problem. As long as that VI doesn't work, forget about the Application Builder.

I suspect that a wrong dll is loaded. Either the (wrong) dll somehow ended up in System32 (also on 64 bit), or somehow the wrong version is loaded (first), or a dependency is missing.

I'd try to open the dll with a CLFN, to see if this results in a meaningful error. Or to use LoadLibrary or a debugger to see if the dll is loaded from the wrong path. But that's a bit technical.

EDIT: See attachment for a VI that returns the path of the dll iff it's in memory. Tested only on 64 bit LV, save and close everything first, it shouldn't but might crash.
