Can not use interop zxing after registering about zxing.net HOT 10 CLOSED

Did you try a restart of Access and/or the whole computer?

from zxing.net.

Yes I did. It did not help.

from zxing.net.

which version of access do you use?

if it works it should like the following screenshot:

from zxing.net.

I had to install VisualStudio2017, run it as administrator, and build zxing.interop. After this it is visible in VBA.
Now the question is, how can this be done without installing visual studio and building it on every computer. The register.com if run from c:\Windows dir does not work (run as Administrator) It is registered successfully but not visible in VBA. I really don't know what is wrong. I checked the registry and it seems to be ok. What is the difference when running it with regasm vs building it from Visual Studio? I am on Windows 10 PRO 64 bit and am using a 32 bit office, so there should not be a problem.

I found this, http://edndoc.esri.com/arcobjects/9.2/NET/9826f81b-278c-49cc-a912-ab8d86f5e91e.htm
and it seems an installer has to be made for it to work. Any ideas?

from zxing.net.

I checked the registry and when run form VS2017 as described above it looks like this:

What I will try next is to put the dll somewhere else, not in c:\windows and run register.cmd on a computer which does not have visual studio installed, to see if it shows up in VBA (it does register no matter what, but does not show up in the VBA)

from zxing.net.

I also noticed that building in VS there is the tlb file created. Can this be the problem? Should I use regasm /tlb ?

from zxing.net.

It seems tlb is needed:
https://www.red-gate.com/simple-talk/dotnet/visual-studio/build-and-deploy-a-.net-com-assembly/

from zxing.net.

I thought the TLB file would be created because of the /tlb parameter:
"%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\regasm.exe" /codebase %~dp0zxing.interop.dll /tlb %~dp0zxing.interop.tlb

I have to check it again.

from zxing.net.

It looks to me that there is an issue if the register.cmd is executed on 64bit windows.
Please try it manually with the following command:
"%SystemRoot%\Microsoft.NET\Framework64\v4.0.30319\regasm.exe" /codebase C:\Windows\System32\zxing.interop.dll /tlb C:\Windows\System32\zxing.interop.tlb

from zxing.net.

I found that running register.cmd DID work OK (as long as the full path to the zxing.interop files did NOT contain spaces).
It did then appear as an available reference in my VB6 projects, but was listed just as

port of the java based barcode scanning library for .net (java zxing 29.07.2019 21:30:35)

and NOT as

ZXing.NET: port of the java based barcode scanning library for .net (java zxing 29.07.2019 21:30:35)

Before trying to rebuild the project in Visual Studio (as suggested above) try looking for this entry.
Hope this helps.
