Could not load file or assembly 'pdftotext' or one of its dependencies.
I am getting the following error when trying to access the admin page of the demo:

Could not load file or assembly 'pdftotext' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Reading some of the results from a search of the forum indicates that this may be a problem specific to 64 bit machines.

Two questions:

1. How do I correct this problem on my development machine (Windows 7 Ultimate 64-bit)?
2. How do I build and deploy to 32-bit production environments as well as 64-bit environments?

For 32-bit machines, copy the 32-bit dlls from C:\Inetpub\wwwroot\Karamasoft\ASP.NET2.0\UltimateSearch\v3.6\Controls\bin to your bin folder and rebuild your app.

For 64-bit machines, copy the 64-bit dlls from C:\Inetpub\wwwroot\Karamasoft\ASP.NET2.0\UltimateSearch\v3.6\Controls\bin\x64 to your bin folder and rebuild your app.

Re: Could not load file or assembly 'pdftotext' or one of its dependencies.
Thanks for the reply. I am able to load the site now but I am getting the following compile time error:

Could not load file or assembly 'pdftotext, Version=2.1.0.0, Culture=neutral, PublicKeyToken=5b5f377bc08a4d32' or one of its dependencies. An attempt was made to load a program with an incorrect format.

The size of the file in the bin folder is 1011 bytes and was extracted from the zip file.

Could you try to use the 32-bit dlls on your development machine as Visual Studio may not work properly with the 64-bit dlls in a design-time environment. If your production machine is 64-bit, you should be able to replace the dlls on it later, but try to use the 32-bit ones during development.

Ah, but then we are back to the orginal posting. The 32 bit dll will not allow the app to load. Or should I just bit the bullet and use the Adobe IFilter?

You shouldn't need to use Adobe IFilter. We have the exact same machine (Windows 7 64-bit) and it works just fine with the 32-bit dlls under the bin folder. Do you have pdftotext.dll, UltimateSearch.dll and UltimateSpell.dll under the bin folder of your own app? Have you tested with the provided sample C# and VB apps? Please check those apps and the dlls under their bin folders.

I have copied files from the 64 bit folder into the bin folder. When I do that, the files fail in compiling however the application rules. When I copy the files either from the bin folder of the controls or demo, the app compiles but I get the runtime error.

The demos do run so there is something else going on which the 64 bit dll doesn't like.

We don't know what exactly is causing the problem with the 64-bit dll in Visual Studio, but as long as you have the sample apps working properly with the 32-bit dlls under the bin folder, you can follow the same pattern to make your app work the same way.
