A 64 bit version of PDF-XChange Viewer/PDF-XChange Editor is being used in conjunction with a version of MS Outlook older than Office 2010.
MS Outlook versions prior to Office 2010 are available only in 32 bit - even when they are used on 64 bit PCs. This results in compatibility issues when 64 bit version of our products are used, in particular with the Shell Extensions provided for preview/search options. We have taken significant measures to resolve this issue - please see below.
The following steps re-register the DLLs and rectify the problem in most cases:
1. Uninstall all PDF-XChange applications.
2. Restart your computer.
3. Download and reinstall the latest versions of the products, which are available here.
If you would rather re-register the Shell Extensions without having to reinstall the products, detailed instructions are available here.
If the steps above do not resolve the issue then please contact us and with the following information:
The version of Windows in use, and whether it is 32 or 64 bit.
The version of MS Office in use.
The name of the installer file used, for example PDFXVwer.zip
The serial key details.
The fastest way to contact us is to use the 'Report a Problem' feature:
