There has been a problem with SDC handing out the wrong version of WB. Post your system information from WB configuration, it will help identify the problem.

Here's mine:-

The files look the same, so you have the right version. Hmmm, dunno what the problem might be then. Which nVidia driver are you using? Have you tried 100.64?  http://www.nzone.com/object/nzone_downloads_rel70betadriver.html They seem to work better than previous versions.

The latest nvidia drivers are the 100.65 whqls, http://downloads.guru3d.com/download.php?det=1582. I hope that helps.

   Nice to know you are up and running.

I had a similar problem, but on XP Pro 64. To fix it, I installed WB 5.5 on a XP Pro 32 machine and copied the install log over to the x64 then "repaired" it using UNWISE.EXE.

Works fine now.

for what it's worth. For those of you running Vista. Most of the installations that need read and write access to system files need administrative permission in order to do so. If you are installing Windowblinds or any Stardock Product from Stardock Central. Stardock Central needs to run as Administrator. If Aero gets disabled type services.msc in the run window and make sure Desktop Window Manager or Desktop Window Manager Session Manager service is running. If it is not start the service manually and see if Aero returns. These solutions worked in my situation where I had similar problems being discussed in this forum.
