Publisher Rocket "Run as Administrator" issue

First, a sincere thank you to the Bottles team.

Got Bottles installed successfully and tested installation with KindleCreateInstall.exe, which fired up just fine. But…

…when I tried to install the program I really need — PublisherRocketSetup.exe — I immediately receive this popup error box:

Installation has failed
Please re-run this installer as a normal user instead of “Run as Administrator”.

I don’t know enough about Bottles to run anything as Administrator. Is this a Bottles message, or is Bottles just passing this message through from the installer’s .EXE?

Thanks in advance.

I’m still doing homework on this. Hints at a possible solution may be found in these locations:

I’m at a loss here. It’s been 14 years since I’ve had regular dealings with Windows. And I’m unfamiliar with WINE syntax. Any help would be appreciated. Thanks.
