vijer 0 Report post Posted August 5, 2018 I'm on Windows 10 64 bit, and using XYplorer instead of File Explorer. Unfortunately, at the moment it requires a 32 bit preview handler. Is there a way to install both 32 bit and 64 bit handlers? Thanks Share this post Link to post Share on other sites
Leslie V. 0 Report post Posted August 6, 2018 Hello @vijer, Thank you for reaching out to us through our Community Forums! We haven't had a request to have both handlers available, so that might not be an option. But if the preview handler is not working, you may try to run a repair on Nitro Pro via Start > Settings > System > Apps & features > Nitro Pro If that doesn't work please try unregistering the DLL file using the following Administrator command (Admin CMD): regsvr32 -u "C:\Program Files\Nitro\Pro 11\NitroPDFPreviewHandler.dll" Then repair Nitro again. I hope that helps! Share this post Link to post Share on other sites
