I would first make sure that the WMIADAP.EXE is not a virus. This file is mentioned on your link to Virustotal.com (tab Behavior): \\?\C:\Windows\system32\wbem\WMIADAP.EXE But as written here: https://www.howto-connect.com/fix-wmiadap-exe-windows-10/ "If you find that it is located in the following directory then it is not a malware and the system is safe." C:\Windows\System32\wbem\files And on other sites often write: " Some malware camouflages itself as WMIADAP.exe, particularly when located in the C:\Windows or C:\Windows\System32 folder. Therefore, you should check the WMIADAP.exe process on your PC to see if it is a threat"

Сan't that be helpful? https://torry.net/files/vcl/vcltools/multilanguage/LangMan_Personal_v2.11.1.zip

I have never worked with TLB, but as a guess... Does method LInvoice.Edit ( or similar ) exist? What if You try to use LInvoice.Edit () instead of LInvoice.New?

This explains why I didn't find anything about this on Google. 😀
