Hi,

Here I want to known one thing clearly, that is I was developed one application in C# with Acrobat SDK.

In my application I am using Acrobat AxAcroPDFLib.AxAcroPDF and  also some other acrobat class.

In my development system i am using Acrobat 7.0.

When my application installed in my client system I am faced different types of problem.

• System 1

OS : XP

Result : Success

• System 2

System Configuration

OS : XP

Acrobat 5.0

Acrobat 7.0

Error : Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)

• System 3

Note:

But I having problem when I am use my application while Adobe Reader 9 is open.

What is problem?

2. Retrieving the COM class factory for component with CLSID {FF76CB60-2E68-2E68-101B-B02E-04021C009402} failed due to the following error: 80080005

• System 4

Problem:

At the time of tool installation the system configuration will be as mention above, after by mistake they installed Adobe Reader 5.0. I faced the problem to use my application ActiveX COM failed

So I was un installed Adobe Reader 5, and tried but I got the following error,

     System.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception      from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

So, I am advised my System Admin team to Re-Install the Acrobat 7.0, after the Re-Installation of Acrobat 7.0, all the problem get solved.

But I want to known what is problem?

And also what is the Adobe COM connection between Acrobat ActiveX and my Application(C#, VB, etc…).

So Please give clear information and guidance...

Thanks & Regard
