How can I Register AcroPDF.dll of version 9.1.0.163 in Windows XP in 32 bit version,so that i can use as PDF viewer control in VS2005.

[lrosenth]

Just install Adobe Acrobat or Reader.

I have Installed the Acrobat Reader of the version 9 in WindowsXp.In VS2005, where i get the AcroPDF.dll in component list and then i add in the project.It working well in the WindowsXp but when i deploy the project in Vista Os of 64 bit.It gives an error i.e "Class not registered HRESULT 0x80040154 REGDB_E_CLASSNOTREG".I have installed the Acrobat Reader of version9 in Vista OS of 64 bit.

[lrosenth]

Are you building a 32 or 64bit application? We only support 32bit applications at this time.

[Pijush Joardar]

Can you Please suggest any FREE PDF viewer that i incorporate into Vs2005 and It support both 64bit and 32 bit OS.

[lrosenth]

On the ADOBE forums, we only have one viewer to recommend...

If you wish to look for alternatives - that's your prerogative - but please do it elsewhere...

I am currently facing a similar problem.  We have some applications that have to be compiled both for 32 and 64 bits.  Is there any news of the acrobat reader control to have full compatibility with 64 bit applications?  If built for 32 bits, the application does not have any problem, at least with the reader control.  There are other controls that may malfunction when built for 32 bits and are running on 64 bit operating systems.  I have done some research on the subject and noticed that while adobe reader is easily going on version 8.1.5, the acropdf dll is still on version 7.x.  Is there a fix in the works?

[lrosenth]

Adobe Reader is currently at version 9.1.3. If you have both Adobe Acrobat

and Adobe Reader installed on your computer, only one of them can register

the DLL.

There is no "fix". You would need a 64bit version of Adobe Reader.

I have Acrobat Reader 9 installed on Windows 7, but AcroPDF.dll does not get registered. Do you know how to resolved the issue. Thanks!

[lrosenth]

What makes you think it is not registered?

[awshiao]

I have an application using PDF Browser Control. It works fine under Windows XP, but got "COMException: Class not registered error 0x80040154". I have tried to register it with regsvr32, but failed. Do you know if AcroPDF - Browser Control is compatible with 64-bit Windows 7/Vista? If not, do you have any plan to support 64-bit systems in the future?

You need to compile the program as 32 bit

in Visual Studio:

Project  / Properties  / Compile  /

    (at bottom) Advanced Compile Options

  (new window) target CPU :  select X86  (not "AnyCPU" or "x64")

works for me in Vista-64

[awshiao]

Yes,that is exactly what happened. Originally, I selected "Any CPU", after changing to "X86" it works. Looks like the AcroPDF.dll is registered, but the app is treated as 64-bit app and it looks at different place in registry. Thank you very much!

I repaired my installation of Adobe Reader and that remedied my problem.
