WixToolset distributed iText7 application has "unknown PDFException" error while works fine in VB debug mode

[leahwang1962]

In a VB.net 64x project, I used itext7(installed through Nuget) to save PDF files. Everything works fine in debug mode(VS2022, framwork4.8). Then I made a installation package with WixToolset(version4.0). Installation on PC works well as I can see the exe application file with needed dll files in the same C:\program files\ folder. But when run this installed program, an error "unknown PDFException" happens. I believe I distributed all the necessary dlls. Can anyone help?

Are you running the installer on your development machine, or on a fresh machine elsewhere?
I assume the second. If so, do a manual copy of the files as per your installer to the target machine, and run it.
If it doesn't work, then your problem is entirely unrelated to WiX.

Bevanweiss, Thanks for your reply. I am running the installer on my development machine, not on a fresh machine. But your conclusion is correct, it's not related to Wix. I figured it out that IText uses some dependence library which no documents mentioned. After adding these dependency dlls in the WixToolset distribution, everything works fine. Sorry for bothering.
