After spending a week of evenings working my way through countless "fix it for WPD preview" threads here & elsewhere, I finally stumbled across the answer. It works on both my Vista-32 laptop and Windows 7 Starter netbook (Asus 1005PE). Since I personally found this whole thing to be maddening, I want to include everything you need to know to pull this off correctly, so apologies for length of this post. Whole deal takes less than 15 minutes.
Version 9.x of Dopus comes with multiview.dll, housed in the Viewers subdirectory of the Dopus install tree. The trick is to get the filters needed to make that MultiViewer relate to WPD files.
The X1 search app is available for a trial evaluation (x1.com). When it installs, the X1 tree includes a "Stellent" subdirectory. That subdirectory has a Filters subdirectory. Those filters include WPD goodness.
(As it happens, I have a 2008 license for X1, so I used that older app installer. Since that dev believes I should pay close to full price for subsequent upgrades after a year, even at same base version number (e.g., 6.1 --> 6.7), I refused to repurchase.)
In any event, I copied the Stellent directory tree to my Dopus tree. Then within Dopus:
............... Settings > Preferences > Viewers
Click on MultiView, then click Configure. When the "MultiView Viewer Plugin Config" popup appears, under "Viewer Libraries", click Locate. Navigate to the Stellent/Filters directory, so that the "Filters" subdirectory is selected. Once selected, click OK til you back out gracefully. If you see an Apply box, be sure to click it to ensure your handiwork "takes".
Shut down Dopus (including the systray icon), then restart and test a WPD file. It should load perfectly, even the latest WPX5 versions! I suspect the newer/current X1 trial app includes the same basic directory tree post-install.
Final note: before I worked out the above fix, I had tried QuickView Plus, via a trial evaluation install. Two insurmountable problems:
- There is no distinct Stellant subdirectory. Instead, there's a series of DLLs which, I presume, are viewers. I'm not a computer programmer, but logic suggested that uninstallng QVP would likely kill whatever magic lies in those viewer DLLs.
- The current version of QVP will not relate to my WPX5 install. Instead, it insists on looking for the old-named Corel Word Perfect Office. Even pointing it to the precise directory does nadda.
Hence, I kept looking til I saw a thread about "Stellant" filters, and eventually lucked up on the X1 connection.
Off-topic, but while I'm here, a quick confirmation. PDF xChange Pro Viewer will work as the pdf viewer, IF you set that app as the default handler for your PDF files.
As someone noted below, there are two spellings appearing throughout the Web, so try both stellAnt and stellEnt. I have no clue which is correct at this point.
