Error loading type library/DLL

[quintonmartin]

during installation, immediately upon executing the "Display progress dialog", this error message displays.

Runtime error in setup script:
Source File: XYZ
Line Number: 312

Error loading type library/DLL

This has only happened on 1 PC so far out of hundreds. The PC is Win7 and has no obvious problems with it with any other software. I suspect the problem is in displaying one of the controls used in the progress dialog form, but am not sure where to look. The progress bar object on the form is the only object on the form that I can tell is different from the prior dialog forms that do show without an error.

I've see this error message mentioned in a couple of other posts, but none had any resolution.
--InstallAware 17 (build 8.6.13)
TIA

Dear Quinton,

the error you are reporting has nothing to do with the Dialog control.

Instead I suspect that your package tries to use a DLL that isn't available or it fail to launch on that system.

In addition, verify the code statement in your script files the error message is referring to (Line Number).

I'm not sure I agree with you. when I run the installation in silent mode with /s, then the install completes successfully. I put debug messages immediately before and after that dialog control is displayed in the MSIcode, and the error is occurring when the dialog is displayed. The message box in the line immediately before displaying the dialog displays, click OK, then the error occurs with the progress dialog never displaying. There is no custom code in that progress dialog. When I run on my PC with ProcessMonitor, There are several DLLs that are loaded in the course of displaying that dialog by the OS. This is what is happening when the progress dialog is displayed as reported by ProcessMonitor.

I haven't been able to run ProcessMonitor on my client's PC as I got past the problem by running in silent mode, but I may have to bother them again to do some debugging on their PC as I am unable to duplicate the problem on any of the 100's of PCs this install has run on to this point.

Dear Quinton,

you are right ... for what you are reporting, it seems that a dll used by that dialog can't be loaded for some reasons on that system.

Anyway it's really strange! All those are system dlls!

Unfortunately, if you have no alternatives to replicate the issue, you have to produce a process log on that machine.

Regards
