Com exception on get_printer - Win 7 64 bit

[alessandro-r]

Hello,

I have downloaded PDFX4API.zip (version 195) and I have installed it on Win7 64 bit.
I build the PDFDriverAPI C# sample on Visual Studio 2010, but it fails at run time. I get an exception in Interop.PXCComLib >> Error code: -2147467259 at the line:

PDFPrinter = (PXCComLib.CPXCPrinter)prnFactory.get_Printer("", "Simple PDF-XChange", "<REG CODE>", "<DEV CODE>");

I have already tried manually to set the reference to the com component, but it doesn't work.
I have also tried to change the platform configuration from AnyCPU to x86.
I get the same result on Win 2008 Server R 2.

On a 32 bit machines it works fine!

Do you have any idea?

Thank you!

Does it work ok when you set the platform configuration to x64 ?

[alessandro-r]

Same result with x64. Com Exception -2147467259

Hello alessandro,

We released a new build last night, and while your problem has not been investigated in details and I can not assure you the new build will fix it - can you please still try with it and let us know how it goes?

Thanks,
Stefan

Hello!

Unfortunately nothing has changed. Same error with the version 196. The driver works properly if you use it directly, but the COM component crashes.
Just to give you an additional information, when you run the sample, a printer without name appears before the crash. I’ve attached a screen capture.

Thank you for any suggestion.

Do you have any news?
We tested the driver also on other 64 bit machines (Win 7, Windows 2008 Server R 2, Windows 2003 Server) but the COM component crashes every time with the exception I mentioned you last time. Same problem also with your sample \Examples\Bin\CExAPI.exe

At the end, on a 64 bit machine it doesn't work. Instead, on a 32 bit machine, it works very fine! We would like to adopt your driver in our solutions, but we need also a 64 bit compatibility.

Are we doing any mistake? Or is it a problem that you already know?

Thank you in advance for your help!

HI alessandro-r,

Can you check if there is pxccom.tlb file located in the same folder where pdfSaver4.exe ? (by default it is: "C:\Program Files\Tracker Software\PDF-XChange 4")
if it is there, please try to run pdfSaver4.exe /RegServer

[alessandro-r]

The file pxccom.tlb is located in "C:\Program Files (x86)\Tracker Software\PDF-XChange 4 API\pdfSaver" folder. The same folder contain the file pdfSaver4.exe

I tryed to run pdfSaver4.exe /RegServer, but nothing has changed. The COM component crashes during the test.

Can you check if example CExAPI.exe works on your side ? (it is located in Bin subfolder of Examples)

[alessandro-r]

Also CExAPI.exe doesn't work. You can see the error message in the attached screenshot

Do you have any Antivirus/Firewall applications installed on this machine? If yes, maybe you can try to check if the problem still exists when they are turned off? Sometimes they may block creation of COM objects - ZoneAlarm for example (I don't know why).
Also, if it is possible, I would like to use TeamViewer to get remove access to your computer to check some registry settings regarding the registration of our API's COM controls.

[alessandro-r]

No antivirus active. About a firewall, there is only Windows Firewall. Same problem if it is deactivate.

We can arrange a teamviewer session (or NTR Support if you prefere) Please, write me an email in order to exchange the connection parameters.
