Error installing Windows update

I’ve tried twice to update Scrivener from 1.2.5 to, and keep getting this error:

There has been an error.
Error trying to install file: destination {(installdir} resolved to an empty value
The application will exit now

(This is a Windows 8 computer, but I had successfully installed the previous version of Scrivener, and it was running fine.)

Solved my problem. It must have been an issue with the fact that I’m logged in as a user account rather than an admin account, and Scrivener had installed itself in my user directory. I simply re-downloaded the new trial version from the site, and then re-installed it again. Works great now. Thanks for putting out this update!
