QuickBooks custom application deployment

Question

I have created an application in c# that connects to our QB in order to post invoice ans such. I am ready to deploy this to out accountants so they can further test the application. This app works fine on my machine, however, when I build my project and take the exe to one of our accountants computers I get an error about "COM class factory, blah, blah Class not registered"

In the past that error would mean that I need to build the c# with x86 and not x64, but I did and still receive the error. I now believe that they do not have the QBFC12.dll registered on their computer like I do.

Is this the problem, and if so then do I have to manually register the dll or is their another way to get that dll on their machine?

Answer 1

I found the answer finally.

1. If you installed QBSDK, explore that folder and locate the Tools folder
2. Under that you should find a Installers folder that has "QBFC12_0Installer.exe"
3. Install the exe on the client machine.
4. Try to run your program, if you encounter another error about "QBXML components are not installed, you will need to re-install QuickBooks and follow from step 1 again. This should get your application up and running for the client.

The person that came the closest and set me on the right track was MikeBr59 so I upvoted him, and posted this incase it helps anyone else.

I think you have to copy it manually and register.

There is no other alternative.

Follow the below steps to copy and register it manually.

1.copy "QBFC12.dll" file into following 2 folders :

a.C:\Windows\System32\

b.C:\Windows\SysWOW64\

2.register the "QBFC12.dll" file using following steps :

open Command Prompt

cd C:\Windows\System32
regsvr32  QBFC12.dll

3.while running the project from visual studio force the platform target as 32 bit -> as the project hasbeen developed in 32 bit using following steps:

Right click on Project
Select Properties
Goto Build Options
Change  "Platform Target" from "ANY CPU" to "X86"

4.now run the Project.
