QBWC error QBWC1013: "Could not start QuickBooks." - quickbooks

Question

I cannot get QuickBooks to start up from the Web Connector. I am passing valid filepath, everything looks right according to the documentation.
QBWC version is 2.1.0.3.0
QB Ver is Premier Contractor Edition 2010
If I have QuickBooks open already, the Web Connector runs fine. If it's not open, I get the QBWC1013 error...
Relevant portion of log:

Answer 1

I'm going to assume that your QWC file is with the correct format.
If may looks something like this
<QBWCXML>
<AppName>Example WS</AppName>
<AppID></AppID>
<AppURL>https://localhost/Quickbooks.asmx</AppURL>
<AppDescription>Example Service Service</AppDescription>
<AppSupport>https://localhost/</AppSupport>
<UserName>Etile</UserName>
<OwnerID>{XXXXB9B1-86F1-4fcc-B1EE-566DE1813D20}</OwnerID>
<FileID>{XXXX4FB5-33D9-4815-AC85-BC87A7E7D1EB}</FileID>
<QBType>QBFS</QBType>
<Scheduler>
<RunEveryNMinutes>1</RunEveryNMinutes>
</Scheduler>
</QBWCXML>
When you add the application to QuickBooks's Web Connector, you will be prompted to allow the application access to QuickBooks data. You need to select the last option "Yes, always; allow access even if QuickBooks is not running"
And don't forget to return the full path to the company file from your Web Service's authenticate() method.
A Sample SOAP Response would be:
<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://developer.intuit.com/">
<SOAP-ENV:Body>
<ns1:authenticateResponse>
<ns1:authenticateResult>
<ns1:string>1e3ea2ed-a734-03e4-ed8c-80eb12f19845</ns1:string>
<ns1:string>C:\Quickbooks Company File.QBW</ns1:string>
</ns1:authenticateResult>
</ns1:authenticateResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Note that if you are using quickbooks-php, the file must be added manually for some reason. The Web Connector documentation and the new QuickBooks integration wiki both lack clarity on this detail.

Answer 2

I was banging my head against the wall on this but after 4 hours on the phone with Intuit and finally having the tier 2 engage there development team they clued me to into some more details on this vague as hell error. When you get this error the problem is not that it can't start quickbooks its that you're request from your server is attempting to open the file incorrectly. Things that will cause this. The name of the file is wrong, the path of the file is wrong. Your request is not formatted correctly.
In my case we had the file name correct but my server was suppose to pull the path of the file which you can confirm in the register at hkey_current_user\software\intuit\qbwebconnector\soapwebservices\ look for companyfile and you'll see the name and full path.
hope this helps someone deal with this vague error.

Answer 3

As log data is showing -> user authenticated, that means .qwc file is in correct format. After authentication, web connector is making a request to QuickBook to connect, which is failing in your case.
Steps to connect to QuickBooks desktop through web connector are :
Run web service and QuickBook desktop application in Admin mode
Name of web service and QuickBook company name should be same
Run QuickBook desktop in multi-user mode so that you can connect QuickBook through web connector as well.
In web service code, if user is authentic then make authReturn[1]=""
// to connect to the company file that is currently openned in QuickBooks
It worked for me.
All the best for you.
