ASPPDF works in one site, not in other site hosted in same server

We are using 3rd Party ActiveX Control - ASPPDF - www.asppdf.com - to print to PDF from our ASP.Net web site.  We have two different web sites that are using this ActiveX Control. These two web sites are running in Client Production Server for past 5 years.

Client have two mirrored IIS production Servers, both have hosted these two sites.

When we recently updated one of the website in Client Production, a strange isssue happened!
The site that I updated in Production (say Site1) is working with ASPPDF perfectly. But the other site (say Site2) which is hosted on the same server that is using ASPPDF, crashes on Print to ASPPDF.

Site 1 is working in Server 1, but crashes in Server 2
Site 1 is crashes in Server 1, but working in Server 2
Both have the same version of source codes.

Error Message:-  Object reference not set to an instance of an object

Previously whenever this crash occurs the reinstallation of ASPPDF will fix this crash - which means this crash is due to something wrong happens with the registration of this ActiveX Control.

I tried re-install ASPPDF - Not helped this time!

I hope this is clear.
Could you please give me some idea, how to fix it ;(  - Please Urgent

Any help would be highly appreciated

Thanks for your suggestion, Mani.
Site 1 and Site 2 are already using two different Application Pools.

When I checked in C:\Program Files (x86)\Persists Software folder, there are two ASPPDF versions installed in both servers
Server 1 - v2.0.0.1 & v1.6.0.10
Server2 - v1.3.0.2 & v1.6.0.10

In bin folder of Site1, Interop.ASPPDFLib.dll is there
In bin folder of Site2, Interop.ASPPDFLib.dll and ASPPDF.dll v1.6.0.5 are present.

But I still not understand why the same site works in one server, while not in other server.

Any thoughts ?

Thanks

Finally my assumption is that Server 1 & Server 2 is registered for different versions of ASPPDF.

Site1 which is working in Server1 may be using the version of ASPPDF that is registered on that server.

Need to check on this

This issue is SOLVED !!!!

Server 1 was installed with ASPPDF New Version, Server 2 was installed with ASPPDF Old Version
Site 1 was using Latest Version in it bin folder, while Site 2 was using Old Version in its bin folder

Now I think you got the issue - and how it got solved.

Solution:-
----------
1. Installed latest version of ASPPDF in Server 2.
2. In Server1 & Server2, copied the ASPPDF DLL (Interop.ASPPDF.dll) from Working Site1's bin folder to Crashing Site2's bin folder
3. Restarted IIS Admin Service in both Servers.

So now both Servers have latest Version of ASPPDF and both Sites are using latest DLL in their bin folders

So now this issue is SOLVED !!!!!
