Question 1: is the license limited by certain version? If so, what is the most recent version for the license we have?

At the moment of purchase, the version of was current (pdf2image.dll). We have never updated it because it worked perfectly.
Currently we are developing an x64 version of our software. Since version did not have x64 component, I have updated version from your Web site.
Apparently, our license did not work. The Converter places watermark on all documents.

Question 2: Can I use the COM wrapper if the application is compiled for AnyCPU platform?

Our application is C# application (.NET Framework 3.5), compiled for AnyCPU platform. When I simply followed your samples regarding placing reference to COM class, everything works fine on x64 platform, but the code:
throws an error 0x8007000B on x86 platform.

Temporarily I have added a simple detection of x86/x64 platform and keep two parts of the code: on x86 it uses old-style DllImport methods of pdf2image.dll, while on x64 it uses COM wrapper. It seems to work, except the watermark problem. I’m wondering how I could remove the old code. Please advice.

Thank you for your help.

Thank you for the prompt answer.

Let me clarify, does the version contain x64 COM wrapper?
If it does, there is no need to upgrade further; the functionality of the older version is quite enough.
In this case, would you please provide me with version I found the Emetrix Order ID for proof of identity.

In case if version does not yet have x64 support, I will have to do some re-evaluation before ordering an upgrade to v.
Sorry for my mistake, I have checked with our engineer just now, the latest version is v2.7.0.0, but not the v2.6.0.1.

V2.7 is support x64 COM wrapper.
