LaurieA, yeah sorry.  I was a bit confused by your post since you said you got it to work but also implied there was a problem with the installer.

hborre, what do you mean by installation workflow?  I'll post any screenshots you need, but I don't understand what exactly you mean by that.

Well, I have absolutely no clue what's going on with this.  Here's some general info, in case it helps:

Brand new ASUS CG5275 Desktop
It's got Kaspersky Anti-Virus installed, so there's no issue with viruses, etc.
Windows 7 Home Premium (64-bit)
Intel Core i5 CPU
650 @ 3.20GHz
8.00 GB RAM (7.89 GB useable)

Like I said, I've got Poser installed at C:Poser 7
I don't use multiple/external Runtimes
All my Poser content (zips, installers, etc.) is stored and unzipped/installed from an External Harddrive

Don't know if it's relevant or not, but when I first tried to install Poser I was having problems.  It would hang up and do nothing when I clicked "Install Poser 7".  In the Windows Task Manager it showed that Poser 7 was "Not Responding" and it wouldn't let me "End Task" which I've never seen happen before with my other comps.  I had to restart my comp to get rid of it.  I eventually tried clicking on "Browse CD" and right-clicked the .exe to install as Administrator and that worked.

If you need any more info, just let me know.
