Open the PowerToys app and go to the File Explorer add-ons section.

The document states that the PDF Previewer in PowerToys is the troublemaker. If the bitness matches or you do not use Adobe Acrobat, check your PowerToys settings. In other words, if you use a 32-bit Outlook, Acrobat Reader should also be 32-bit (and the same with 64-bit versions). Again, check its architecture, which should match the one in Outlook. Open the Adobe Acrobat Reader app and go to Help > About Adobe Acrobat Reader.Launch Outlook and go to File > Office Account > About Outlook.You can fix the first problem by ensuring you use the 32 or 64-bit version of Microsoft Outlook and Adobe Acrobat Reader. Al-Qudsi" site:" to find all of the super-awesome tools.Microsoft says that two things trigger the error message: mismatch of bitness in Outlook and Adobe Acrobat, and the PDF preview module in the PowerToys app. Why haven't you published these PowerToys publicly btw? So awesome work porting these to 64-bit!!! Also, all the great freebie tools should be listed on one single page. I love the NeoSmart blog as well (though it's almost dead these days LOL). I also can't thank you enough for the great great free tools you've developed like ToolTipFixer, CHMOD-Win, i-Reboot and EasyBCD. And if possible the Super-Fast User Switcher (still works without any issues on 32-bit XP but not 64-bit) and the Background Switcher which was also another powertoy that was retired. I would love Task Switcher and TimerShot for XP 64-bit though. On 圆4 XP/Src 03, PowerCalc, ClearType Tuner, CmdPrompt here, HTML Slideshow Generator all work (although they're not 64-bit native). I am a greedy Windows fanboy so I would love any tools and goodies you have ported to 64-bit!!!!!!! I am also beyond shocked (pleasantly) how perfect the 64-bit TweakUI is! Can't notice ANY difference from the 32-bit TweakUI. Yes the VDM works FANTASTICALLY PERFECT on my XP Professional 圆4 edition.
